R is a programming language meant for statistical computing and data science.
Just like HTML and other text formats, you can also take advantage of an editor built specifically for editing Markdown documents to ease your job. Typically, a Markdown editor has a clean interface to help you keep focused on what you are writing. Mac users have more options of Markdown editor than other platforms. ONE colud also use the new Visual Studio Code Editor (my favorite Editor by now) or Atom or MacVIM or Xcode,Netbeans,Eclipse,IntellijIDEA (basically any Programming IDE does also Support XML Syntax Highlighting and most of the also have Code Completition) if you need also DTD/XSD Validation the you need to take a closer look – konqui Aug 11 '16 at 18:55.

A text editor is a type of computer program that edits plain text. Such programs are sometimes known as 'notepad' software, following the naming of Microsoft Notepad. Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming languagesource code.
Plain text vs. rich text
There are important differences between plain text (created and edited by text editors) and rich text (such as that created by word processors or desktop publishing software).
Plain text exclusively consists of character representation. Each character is represented by a fixed-length sequence of one, two, or four bytes, or as a variable-length sequence of one to four bytes, in accordance to specific character encoding conventions, such as ASCII, ISO/IEC 2022, UTF-8, or Unicode. These conventions define many printable characters, but also non-printing characters that control the flow of the text, such as space, line break, and page break. Plain text contains no other information about the text itself, not even the character encoding convention employed. Plain text is stored in text files, although text files do not exclusively store plain text. In the early days of computers, plain text was displayed using a monospace font, such that horizontal alignment and columnar formatting were sometimes done using whitespace characters. For compatibility reasons, this tradition has not changed.
Rich text, on the other hand, may contain metadata, character formatting data (e.g. typeface, size, weight and style), paragraph formatting data (e.g. indentation, alignment, letter and word distribution, and space between lines or other paragraphs), and page specification data (e.g. size, margin and reading direction). Rich text can be very complex. Rich text can be saved in binary format (e.g. DOC), text files adhering to a markup language (e.g. RTF or HTML), or in a hybrid form of both (e.g. Office Open XML).
Text editors are intended to open and save text files containing either plain text or anything that can be interpreted as plain text, including the markup for rich text or the markup for something else (e.g. SVG).
Before text editors existed, computer text was punched into cards with keypunch machines. Physical boxes of these thin cardboard cards were then inserted into a card-reader. Magnetic tape and disk 'card-image' files created from such card decks often had no line-separation characters at all, and assumed fixed-length 80-character records. An alternative to cards was punched paper tape. It could be created by some teleprinters (such as the Teletype), which used special characters to indicate ends of records.
The first text editors were 'line editors' oriented to teleprinter- or typewriter-style terminals without displays. Commands (often a single keystroke) effected edits to a file at an imaginary insertion point called the 'cursor'. Edits were verified by typing a command to print a small section of the file, and periodically by printing the entire file. In some line editors, the cursor could be moved by commands that specified the line number in the file, text strings (context) for which to search, and eventually regular expressions. Line editors were major improvements over keypunching. Some line editors could be used by keypunch; editing commands could be taken from a deck of cards and applied to a specified file. Some common line editors supported a 'verify' mode in which change commands displayed the altered lines.
When computer terminals with video screens became available, screen-based text editors (sometimes called just 'screen editors') became common. One of the earliest full-screen editors was O26, which was written for the operator console of the CDC 6000 series computers in 1967. Another early full-screen editor was vi. Written in the 1970s, it is still a standard editor on Unix and Linux operating systems. Also written in the 1970s was the UCSD Pascal Screen Oriented Editor, which was optimized both for indented source code as well as general text.Emacs, one of the first free and open source software projects, is another early full-screen or real-time editor, one that was ported to many systems. A full-screen editor's ease-of-use and speed (compared to the line-based editors) motivated many early purchases of video terminals.
The core data structure in a text editor is the one that manages the string (sequence of characters) or list of records that represents the current state of the file being edited.While the former could be stored in a single long consecutive array of characters,the desire for text editors that could more quickly insert text, delete text, and undo/redo previous edits led to the development of more complicated sequence data structures.A typical text editor uses a gap buffer, a linked list of lines (as in PaperClip), a piece table, or a rope, as its sequence data structure.
Types of text editors
Some text editors are small and simple, while others offer broad and complex functions. For example, Unix and Unix-like operating systems have the pico editor (or a variant), but many also include the vi and Emacs editors. Microsoft Windows systems come with the simple Notepad, though many people—especially programmers—prefer other editors with more features. Under Apple Macintosh's classic Mac OS there was the native SimpleText, which was replaced in Mac OS X by TextEdit, which combines features of a text editor with those typical of a word processor such as rulers, margins and multiple font selection. These features are not available simultaneously, but must be switched by user command, or through the program automatically determining the file type.
Most word processors can read and write files in plain text format, allowing them to open files saved from text editors. Saving these files from a word processor, however, requires ensuring the file is written in plain text format, and that any text encoding or BOM settings won't obscure the file for its intended use. Non-WYSIWYG word processors, such as WordStar, are more easily pressed into service as text editors, and in fact were commonly used as such during the 1980s. The default file format of these word processors often resembles a markup language, with the basic format being plain text and visual formatting achieved using non-printing control characters or escape sequences. Later word processors like Microsoft Word store their files in a binary format and are almost never used to edit plain text files.
Some text editors can edit unusually large files such as log files or an entire database placed in a single file. Simpler text editors may just read files into the computer's main memory. With larger files, this may be a slow process, and the entire file may not fit. Some text editors do not let the user start editing until this read-in is complete. Editing performance also often suffers in nonspecialized editors, with the editor taking seconds or even minutes to respond to keystrokes or navigation commands. Specialized editors have optimizations such as only storing the visible portion of large files in memory, improving editing performance.
Some editors are programmable, meaning, e.g., they can be customized for specific uses. With a programmable editor it is easy to automate repetitive tasks or, add new functionality or even implement a new application within the framework of the editor. One common motive for customizing is to make a text editor use the commands of another text editor with which the user is more familiar, or to duplicate missing functionality the user has come to depend on. Software developers often use editor customizations tailored to the programming language or development environment they are working in. The programmability of some text editors is limited to enhancing the core editing functionality of the program, but Emacs can be extended far beyond editing text files—for web browsing, reading email, online chat, managing files or playing games and is often thought of as a Lisp execution environment with a Text User Interface. Emacs can even be programmed to emulate Vi, its rival in the traditional editor wars of Unix culture.
An important group of programmable editors uses REXX[a] as a scripting language. These 'orthodox editors' contain a 'command line' into which commands and macros can be typed and text lines into which line commands[b] and macros can be typed. Most such editors are derivatives of ISPF/PDFEDIT or of XEDIT, IBM's flagship editor for VM/SP through z/VM. Among them are THE, KEDIT, X2, Uni-edit, and SEDIT.
A text editor written or customized for a specific use can determine what the user is editing and assist the user, often by completing programming terms and showing tooltips with relevant documentation. Many text editors for software developers include source code syntax highlighting and automatic indentation to make programs easier to read and write. Programming editors often let the user select the name of an include file, function or variable, then jump to its definition. Some also allow for easy navigation back to the original section of code by storing the initial cursor location or by displaying the requested definition in a popup window or temporary buffer. Some editors implement this ability themselves, but often an auxiliary utility like ctags is used to locate the definitions.
- Find and replace – Text editors provide extensive facilities for searching and replacing text, either on groups of files or interactively. Advanced editors can use regular expressions to search and edit text or code.
- Cut, copy, and paste – most text editors provide methods to duplicate and move text within the file, or between files.
- Ability to handle UTF-8 encoded text.
- Text formatting – Text editors often provide basic visual formatting features like line wrap, auto-indentation, bullet list formatting using ASCII characters, comment formatting, syntax highlighting and so on. These are typically only for display and do not insert formatting codes into the file itself.
- Undo and redo – As with word processors, text editors provide a way to undo and redo the last edit, or more. Often—especially with older text editors—there is only one level of edit history remembered and successively issuing the undo command will only 'toggle' the last change. Modern or more complex editors usually provide a multiple-level history such that issuing the undo command repeatedly will revert the document to successively older edits. A separate redo command will cycle the edits 'forward' toward the most recent changes. The number of changes remembered depends upon the editor and is often configurable by the user.
- Macro or procedure definition: to define new commands or features as combinations of prior commands or other macros, perhaps with passed parameters, or with nesting of macros.
- Profiles to retain options set by the user between editing session.
- Profile macros with names specified in, e.g., environment, profile, executed automatically at the beginning of an edit session or when opening a new file.
- Multi-file editing: the ability to edit multiple files during an edit-session, perhaps remembering the current-line cursor of each file, to insert repeated text into each file, copy or move text among files, compare files side-by-side (perhaps with a tiled multiple-document interface), etc.
- Multi-view editors: the ability to display multiple views of the same file, with independent cursor tracking, synchronizing changes among the windows but providing the same facilities as are available for independent files.
- Collapse/expand, also called folding: The ability to temporarily exclude sections of the text from view. This may either be based on a range of line numbers or on some syntactic element, e.g., excluding everything between a BEGIN; and the matching END;.
- Column-based editing; the ability to alter or insert data at a particular column, or to shift data to specific columns.
- Data transformation – Reading or merging the contents of another text file into the file currently being edited. Some text editors provide a way to insert the output of a command issued to the operating system's shell. Also, a case-shifting feature could translate to lowercase or uppercase.
- Filtering – Some advanced text editors allow the editor to send all or sections of the file being edited to another utility and read the result back into the file in place of the lines being 'filtered'. This, for example, is useful for sorting a series of lines alphabetically or numerically, doing mathematical computations, indenting source code, and so on.
- Syntax highlighting – contextually highlights source code, markup languages, config files and other text that appears in an organized or predictable format. Editors generally allow users to customize the colors or styles used for each language element. Some text editors also allow users to install and use themes to change the look and feel of the editor's entire user interface.
- Extensibility - a text editor intended for use by programmers must provide some plugin mechanism, or be scriptable, so a programmer can customize the editor with features needed to manage individual software projects, customize functionality or key bindings for specific programming languages or version control systems, or conform to specific coding styles.
Some editors include special features and extra functions, for instance,
- Source code editors are text editors with additional functionality to facilitate the production of source code. These often feature user-programmable syntax highlighting and code navigation functions as well as coding tools or keyboard macros similar to an HTML editor (see below).
- Folding editors. This subclass includes so-called 'orthodox editors' that are derivatives of Xedit. Editors that implement folding without programing-specific features are usually called outliners (see below).
- IDEs (integrated development environments) are designed to manage and streamline large programming projects. They are usually only used for programming as they contain many features unnecessary for simple text editing.
- World Wide Web authors are offered a variety of HTML editors dedicated to the task of creating web pages. These include: Dreamweaver, KompoZer and E Text Editor. Many offer the option of viewing a work in progress on a built-in HTML rendering engine or standard web browser.
- Most web development is done in a dynamic programming language such as Ruby or PHP using a source code editor or IDE. The HTML delivered by all but the simplest static web sites is stored as individual template files that are assembled by the software controlling the site and do not compose a complete HTML document.
- Mathematicians, physicists, and computer scientists often produce articles and books using TeX or LaTeX in plain text files. Such documents are often produced by a standard text editor, but some people use specialized TeX editors.
- Outliners. Also called tree-based editors, because they combine a hierarchical outline tree with a text editor. Folding (see above) can be considered a specialized form of outlining.
- Collaborative editors allow multiple users to work on the same document simultaneously from remote locations over a network. The changes made by individual users are tracked and merged into the document automatically to eliminate the possibility of conflicting edits. These editors also typically include an online chat component for discussion among editors.
- Distraction-free editors provide a minimalistic interface with the purpose of isolating the writer from the rest of the applications and operating system, thus being able to focus on the writing without distractions from interface elements like a toolbar or notification area.
Programmable editors can usually be enhanced to perform any or all of these functions, but simpler editors focus on just one, or, like gPHPedit, are targeted at a single programming language.
- File viewer – does not change file, faster for very large files and can be more secure
- Hex editor – used for editing binary files
- Stream editor – used for non-interactive editing
- ^Originally macros were written in assembler, CLIST (TSO), CMS EXEC (VM), EXEC2 (VM/SE) or PL/I, but most users dropped CLIST, EXEC and EXEC2 once REXX was available.
- ^A line command is a command typed into the sequence number entry area associated with a specific line of text and whose scope is limited to that line, or, in the case of a block command, associated with the block of lines between the beginning and ending line commands. An example of the latter would be typing the command ucc (block upper case) into the entry areas of two lines; this has the same effect as typing uc (upper case) into the entry area of each line in the range.
