问题 If a have a latex document, how can I read some key-value pairs from a file an insert them into the document? Something like this: Latex code: customer ID: ${customerID} Text file: customerID=123456 And the resulting .pdf file should contain the customer ID. 回答1: We can always write a perl script to expand them... defs.txt: customerID=123456 customerTel=22530000000 doc.tex: \documentclass{article} \begin{document} latex customer ID: ${customerID} and ${address} costum telphone ID: $

问题 I just trying to get $\10^{-1}$ in a table in Shiny, but it is not working. I'm trying the following code (thanks in advance): ui.R : require(shiny) shinyUI(tableOutput('mytable') ) server.R : require(shiny) shinyServer(function(input, output){ output$mytable <- renderTable({ df <- data.frame(A = c("$\\10^{-1}$", 33.1, 6),B = c(111111, 3333333, 3123.233)) df }, sanitize.text.function = function(x) x) }) 回答1: You can use mathJAX in shiny: require(shiny) ui <- shinyUI( fluidPage( withMathJax()

问题 I'm looking for some LaTeX template for creating quality output. On R-bloggers I've bumped on Frank Harrel's Rreport package. Due to my quite modest LaTeX abilities, only a user-friendly (and noob-friendly) interface should suffice. Here's a link to an official website. I'm following the instructions, but I cannot manage to install an app. I use Ubuntu 9.10, R version is 2.10.1 (updated regularly from UCLA's CRAN server), and of course, cvs is installed on my system. Now, I'd like to know if

问题 This existing question covers a way to alternate row colors in a latex table by post-processing the output from print.xtable() , but I think it's possible to achieve the same thing by using the add.to.row argument of print.xtable() as described on stats.stackexchange, avoiding the need for post-processing, which is nice with Sweave. That answer deals with coloring the background of one specific row, but I think it can be extended to coloring all the odd rows. The problem I'm running into has

问题 Let's say I have written the following tiny .Rnw file: \documentclass{article} \usepackage[utf8]{inputenc} \usepackage{Sweave} \usepackage{tikz} \usepackage{pgf} \begin{document} <<>>= sessionInfo() @ \end{document} I then can go to R and use sweave to translate the .Rnw file into a .tex file Once this is done the latex interpreter can be called and because I used \usepackage{Sweave} Latex knows how to handle the sweave specific code tags. When I first did this procedure I got the common

问题 I'm using Python to process some plain text into LaTeX, so I need to be able to write things like \begin{enumerate} or \newcommand to a file. When Python writes this to a file, though, it interprets \b and \n as special characters. How do I get Python to write \newcommand to a file, instead of writing ewcommand on a new line? The code is something like this ... with open(fileout,'w',encoding='utf-8') as fout: fout.write("\begin{enumerate}[1.]\n") Python 3, Mac OS 10.5 PPC 回答1: One solution is

问题 I've hit an annoying problem in LaTeX. I've got a tex file of about 1000 lines. I've already got a few figures, but when I try to add another figure, It barfs with: ! Undefined control sequence. <argument> ... \sf@size \z@ \selectfont \@currbox l.937 \begin{figure}[t] If I move the figure to other parts of the file, I can get similar errors on different lines: ! Undefined control sequence. <argument> ... \sf@size \z@ \selectfont \@currbox l.657 \paragraph {A Centering Algorithm} If I comment

问题 When using csquotes quotation marks are added by csquotes according to context. This is done by marking up quotation with the \enquote macro, i.e. as \enquote{text} . When exporting to LaTeX from Org-mode quotation marks are marked up as `` and '' , e.g. as ``text'' . Can Org-mode export to LaTeX with quotations marked up by \enquote ? I found http://comments.gmane.org/gmane.emacs.orgmode/43689 where such a feature is being planned but I do not understand whether it was implemented. On a

问题 I am using ipython notebook to write latex equations with the following modules from IPython.display import display, Math, Latex a simple example code might look like: display(Math('a = \\frac{1}{2}')) display(Math('b = \\frac{1}{3}')) display(Math('c = \\frac{1}{4}')) Which would output: a = 1/2 b = 1/3 c = 1/4 in a pretty print format. Is there a way that I can somehow align this in columns like: a = 1/2 b = 1/3 c = 1/4 ? I know that the markup allows HTML usage, but this markup is entered

问题 I am aware that *** is Pandoc's Markdown for a horizontal rule. This horizontal line looks good on HTML, but if I knit my Markdown into a pdf the horizontal rule only runs half the width of the pdf, and it is centered. This combination just makes the horizontal rule look plain ugly. How do I properly put a horizontal rule in my R Markdown that can render properly to both HTML and pdf? Properly == full length/full width . And while I'm at it, can I format the horizontal rule (color, thickness,
