3 Intro: L A TEX L A TEX (pronounced Lah-tech or Lay tech, no s ) is a markup language. It is not WYSIWYG What You See Is What You Get Figure 1: L A TEX Source and Complied PDF

8 Intro: L A TEX 1 Write L A TEX code 2 Compile 3 View output 4 Return to Step 1 for editing

9 Intro: LYX 1 LYXis a graphical editor built on top of a L A TEX processor. 2 It is not WYSIWYG either. It is WYSIWYM (What You See Is What You Mean) Eg. You CANNOT add distance by adding more than one spaces and you CANNOT change layout by clicking and dragging. 3 It displays most L A TEX effects while editing but it does NOT compile while editing.

10 Installing LYX A working L A TEX environment. Download the latest LYX from lyx.org or install from package manager (linux). This tutorial is based LYX Alternatively, you can compile LYX directly from source, that enable you to use the latest beta version.

11 Basic Text Editing 1 File -> New (or click icon) 2 Let s type something. Can you type two spaces between two words? Want will \ do? 3 Preview this document by View -> View[PDF(pdflatex)] (or click icon) Figure 2: Basic Text Editing Menu

12 More Advanced Text Editing Layout styles list (droplist in the top-left corner in the toolbar) Add a numbered list and a itemized list. Add title, author and abstract. Add a section. Text Style Change the font, size, color and italicize etc. What is going on? View the L A TEX code: View -> View Source Figure 3: Advanced Text Editing

13 More Advanced Text Editing Layout styles list (droplist in the top-left corner in the toolbar) Add a numbered list and a itemized list. Add title, author and abstract. Add a section. Text Style Change the font, size, color and italicize etc. What is going on? View the L A TEX code: View -> View Source Figure 3: Advanced Text Editing

14 Figure and Table 1 Directly insert a picture or table. (Equivalent to L A TEX code \includegraphics and \begin{tabular}) Insert -> Table or Insert -> Graphics 2 Floating tables and figures will be placed automatically to achieve best layout. 1 Insert -> Float -> Figure/Table (Equivalent to L A TEX figure and table environment.) 2 Insert the table or graphics. 3 For graphics: In the dialog, you can set scaling, rotations etc. Reopen this dialog by clicking the graphics. 4 Use Paragraphic Setting to put it at the center. 5 Right click the gray float label to change placement options. Figure 4: Float Label Figure 5: Paragraph Setting

15 Math Editor 1 Simply click on Insert -> Math -> Inline formula or Display formula. 2 Start typing! Like you do in L A TEX. LYX will automatically complete math command for you. Figure 6: Math Completion 3 Use math toolbar. View -> Toolbars -> Math etc. You can insert matrix, case and symbols by clicking. 4 Define math marco: Insert -> Math -> Marco

16 Export To Different Formats 1 If you have an existing L A TEX file, you can import it into LYX You can also import Table(CSV), RTF file, and?sweave? File -> Import 2 Since LYXuses L A TEX engine, it can be exported.tex source file and any format L A TEX supports. Eg. DVI, HTML, Open Document, etc. You can choose to use many different typesetting engines. (Default is pdflatex) File -> Export

17 Cross Reference 1 Insert -> Label (\label{}) name a formula figure or table. 2 Insert -> Cross-reference (\ref{}) to refer to it. (Figure 7) Figure 7: Basic Text Editing Menu

18 Citation 1 Go to the place in your document where you want the references to be presented (presumably, the end. You can also have reference at the end of each section). Insert -> Lists & TOC -> BibTEX Bibliography 2 In the dialog, add -> browse look for the.bib file where your bibliography is stored. You can add multiple libraries... 3 Back in Menu, change style. 4 See various styles in techtalk/632.htm~mainframe 5 Insert -> Citation to cite in the text.

19 Citation with Zotero/LyZ 1 If you use Zotero and LYX, you should use LyZ to connect them. 2 Zotero is a Firefox plugin that allows you to collect and manage citation info, abstract, PDF from arxiv.org, journal website or library/amazon catalog. 3 LyZ is a plug-in that connects Zotero and LYX. The citation information in Zotero can be exported to BibTex file and the LYX document by one-click. 4 Instructions see:

20 Document Settings Document -> Setting 1 Document Class: setting L A TEX preamble \documentclass 2 Page Layout: choose page size etc. 3 Float Placement: Eg: Set global float placement to be Here definitely. ( \begin{figure}[h] ) 4 Change default font, bullet style, color, page margin etc.

21 L A TEX Code, ERT and Preamble 1 What if there isn t a button corresponding to the L A TEX command you want? 1 You CANNOT change the L A TEX source directly. 2 You insert raw L A TEX command as ERT (Evil Red Text) in your document. 3 Or, you can insert raw L A TEX command into document preamble. 2 Drawbacks of using raw L A TEX code: 1 LYXwill not be able to display the result of raw L A TEX code. 2 Inserting raw L A TEX code will make it more error-prone. 3 If you have a full latex file, importing it into LYXwould be better.

22 L A TEX Code, ERT and Preamble 1 Preamble Document -> Settings -> L A TEX Preamble If package simpsons has been installed, add: \usepackage{simpsons} 2 When to use ERT? 1 You have a big trunk of L A TEX code (e.g. a table) 3 When you want to do something fancy, like this, add [3] after the \item. 2 Or when you want to use commands from third-party packages. \Bart \Left\Homer

23 Key Bindings LYX is not faster than a good L A TEX editor. AUCTEX in Emacs has key binding for fonts, environments and math symbols. Customized key bindings in LYX: Preference -> Editing -> Shortcuts Choose shortcut style and search for key-bindings Figure 8: Change Key Bindings

24 Sweave Sweave is a tool in the R language for dynamic report generation. R code can be mixed into a L ATEX document. It will be executed in R. The results are written into the TEX output. Workflow.Rnw file contains L A TEX and R codes In R, run Sweave("file.Rnw"). working directory. Note.Rnw file must be in the R A file.tex file will be generated, compile to obtain PDF.

25 Sweave R code chunk begins after < <> >= and ends In R, run: Sweave( file.rnw ) to generate a file.tex file. Figure 9: A Look at.rnw source code and output

26 Use Sweave in LYX 1 Document -> Settings -> Modules Select Sweave 2 Set global Sweave options at the beginning of the document: Insert -> Custom Insets -> Sweave Options E.g. echo=false to suppress all R code 3 Write R code in LYX: Switch to the Chunk environment in the layout styles list. For more detail: Official LyX manual for Sweave. (Do not use tutorials based on LYX version 1.X)

27 Beamer Beamer is a L A TEX class for creating slides for presentations. This presentation is made using Beamer in LYX. To use Beamer in LYX: Document -> Settings -> Document Classes: Choose Presentation (Beamer ) The better way: modify a template. Beamer examples: L YX file for this presentation:

28 Frames and Overlays Frames are the environment for defining slides. You can do basically anything (and more) in frames that you can do in a simple L A TEX document To add a frame: Switch to the BeginFrame environment in the layout styles list This allows you to present things in any order. You can also use overlay specifications to create overlays. Add ERT <4-> after \item if you want this to the 4th item to appear.

32 Blocks and Theorems A Eample Block You can have boxed texts by using Block or Theorem Switch to various Block or Theorems environment in the layout styles list. Theorem Insert pause environment from the layout styles list to achieve an overlay effect.

34 We can use Sweave and Beamer together in LYX Set Document Class to presentation (beamer) Add Sweave module. There is an incompatibility between Sweave and Beamer. Need to install and use Beamer Fragile module. For more information about how to install it:

35 Use Fragile Frame with Sweave output To use a Fragile Frame : Create a new paragraph and insert an EndFrame environment Then create another paragraph and access Insert > Custom Insets > FragileFrame If you want to use a title for the frame, then within the Fragile Frame inset do Insert > Custom Insets > FragileTitle An example of verbatim Sweave results: Some Sweave code > (x < ) [1] 4
