Please answer the following question: Information: - X (named "ex" , plural "exes") is the 24th and antepenultimate letter in the modern English alphabet and the ISO basic Latin alphabet. - Sweave is a function in the statistical programming language R that enables integration of R code into LaTeX or LyX documents . The purpose is '' to create dynamic reports , which can be updated automatically if data or analysis change '' . The data analysis is performed at the moment of writing the report , or more exactly , at the moment of compiling the Sweave code with Sweave ( i.e. , essentially with R ) and subsequently with LaTeX . This can facilitate the creation of up - to - date reports for the author . Because the Sweave files together with any external R files that might be sourced from them and the data files contain all the information necessary to trace back all steps of the data analyses , Sweave also has the potential to make research more transparent and reproducible to others . However , this is only the case to the extent that the author makes the data and the R and Sweave code available . If the author only publishes the resulting PDF document or printed versions thereof , a report created using Sweave is no more transparent or reproducible than the same report created with other statistical and text preparation software . - Microsoft Word is a word processor developed by Microsoft. It was first released on October 25, 1983 under the name "Multi-Tool Word" for Xenix systems. Subsequent versions were later written for several other platforms including IBM PCs running DOS (1983), Apple Macintosh running Classic Mac OS (1985), AT&T Unix PC (1985), Atari ST (1988), OS/2 (1989), Microsoft Windows (1989), SCO Unix (1994), and macOS (2001). Commercial versions of Word are licensed as a standalone product or as a component of Microsoft Office, Windows RT or the discontinued Microsoft Works suite. Microsoft Word Viewer and Office Online are freeware editions of Word with limited features. - Typesetting is the composition of text by means of arranging physical types or the digital equivalents. Stored letters and other symbols (called sorts in mechanical systems and glyphs in digital systems) are retrieved and ordered according to a language's orthography for visual display. Typesetting requires the prior process of designing a font (which is widely but erroneously confused with and substituted for typeface). One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission. - WYSIWYG is an acronym for "what you see is what you get". In computing, a WYSIWYG editor is a system in which content (text and graphics) can be edited in a form closely resembling its appearance when printed or displayed as a finished product, such as a printed document, web page, or slide presentation. - The term cross-reference can refer to either: - Broadly, a citation is a reference to a published or unpublished source (not always the original source). More precisely, a citation is an abbreviated alphanumeric expression embedded in the body of an intellectual work that denotes an entry in the bibliographic references section of the work for the purpose of acknowledging the relevance of the works of others to the topic of discussion at the spot where the citation appears. Generally the combination of both the in-body citation and the bibliographic entry constitutes what is commonly thought of as a citation (whereas bibliographic entries by themselves are not). References to single, machine-readable assertions in electronic scientific articles are known as nanopublications, a form of microattribution. - WYSIWYM (an acronym for "what you see is what you mean") is a paradigm for editing a structured document. It is an adjunct to the better-known WYSIWYG (what you see is what you get) paradigm, which displays a formatted document on screen as it will appear in only one mode of presentation. - A word processor is an electronic device or computer software application, that performs the task of composing, editing, formatting, and printing of documents. - TeX (or , see below) is a typesetting system (or "formatting system") designed and mostly written by Donald Knuth and released in 1978. Together with the Metafont language for font description and the Computer Modern family of typefaces, TeX was designed with two main goals in mind: to allow anybody to produce high-quality books using minimal effort, and to provide a system that would give exactly the same results on all computers, at any point in time. TeX is free software, which has made it more accessible to a wider range of users. - MiKTeX is a distribution of the TeX/LaTeX typesetting system for Microsoft Windows. It also contains a set of related programs. MiKTeX provides the tools necessary to prepare documents using the TeX/LaTeX markup language, as well as a simple tex editor: TeXworks. The name comes from Christian Schenk's login: MiK for Micro-Kid. - In computing, plain text is the data (e.g. file contents) that represent only characters of readable material but not its graphical representation nor other objects (images, etc.). It may also include a limited number of characters that control simple arrangement of text, such as line breaks or tabulation characters. Plain text is different from formatted text, where style information is included, and from "binary files" in which some portions must be interpreted as binary objects (encoded integers, real numbers, images, etc.). - A document processor is a computer application that superficially resembles a word processorbut emphasizes the visual layout of the document's components, above creation and formatting of text. Document processor tools are not just typical document elementsparagraphs, lists, headers, etc. The primary attraction of a document processor is the ability to program documents with strong layout controls and powerful conditional automatic formatting rules that create structured documents. This facilitates creating large numbers of similar elements generated and reformatted for different media with little human effort. - TeX Live is a free software distribution for the TeX typesetting system that includes major TeX-related programs, macro packages, and fonts. It is the replacement of its no-longer supported counterpart teTeX. It is now the default TeX distribution for several Linux distributions such as openSUSE, Fedora, Debian, Ubuntu and Gentoo. Other Unix operating systems like OpenBSD, FreeBSD and NetBSD have also converted from teTeX to TeX Live. - Digital distribution (also called content delivery, online distribution, or electronic software distribution (ESD), among others) is the delivery or distribution of media content such as audio, video, software and video games. The term is generally used to describe distribution over an online delivery medium, such as the Internet, thus bypassing physical distribution methods, such as paper, compact discs, and VHS videocassettes. The term online distribution is typically applied to freestanding products; downloadable add-ons for other products are more commonly known as downloadable content. With the advancement of network bandwidth capabilities, online distribution became prominent in the 21st century. - Formatted text, styled text, or rich text, as opposed to plain text, has styling information beyond the minimum of semantic elements: colours, styles (boldface, italic), sizes, and special features (such as hyperlinks). - LyX (styled as formula_1; pronounced ) is an open source document processor based on top of the LaTeX typesetting system. Unlike most word processors, which follow the WYSIWYG ("what you see is what you get") paradigm, LyX has a WYSIWYM ("what you see is what you mean") approach, where what shows up on the screen is only an approximation of what will show up on the page. - LaTeX (, also pronounced as , a shortening of Lamport TeX) is a document preparation system. When writing, the writer uses plain text as opposed to formatted text, as in WYSIWYG word processors like Microsoft Word or LibreOffice Writer. The writer uses markup tagging conventions to define the general structure of a document (such as article, book, and letter), to stylise text throughout a document (such as bold and italic), and to add citations and cross-references. A TeX distribution such as TeX Live or MikTeX is used to produce an output file (such as PDF or DVI) suitable for printing or digital distribution. Within the typesetting system, its name is stylised as LaTeX. Given the paragraphs above, decide what entity has the relation 'instance of' with 'free software'.
