sweave

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 to do with the add.to.row argument, making the length of list pos equal the length of character vector

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 error that the Sweave.sty file could not be found. I googled and could solve the problem by typing the

This I am sure is really basic stuff. I am just beginning using gvim and latex-suite. However I would like latex-suite to load when I edit a sweavefile with.Rnw extension. my .vimrc looks like this " These settings are needed for latex-suite filetype indent on filetype plugin on filetype on let g:tex_flavor='latex' set grepprg=grep\ -nH\ $* "let g:Tex_Folding=0 "I don't like folding. set iskeyword+=: and I guess there is some option I can set here that makes vim treat Rnw as .tex? Put a file in /usr/share/vim/vimfiles/ftdetect (for global) or .vim/ftdetect (for local) called Rnw.vim that looks

I am extending a question I posted here: If-Else Statement in knitr/Sweave using R variable as conditional I would like to use an if-else syntax in LaTeX so that, depending on the value of an R variable (say x), one of two LaTeX text paragraphs are output. If x>0, then the LaTeX paragraph has a figure and a table. However, if x<0, then the LaTeX paragraph has just a figure (and no table). I have a MWE that works and is based on the checked answer at the previous post: \documentclass[12pt,english,nohyper]{tufte-handout} \usepackage{tabularx} \usepackage{longtable} \begin{document} <<setup, echo

I'm having the same issue as this question : When I open any .Rnw file, R Studio says that I have no TeX Distribution installed: I'm using Ubuntu 14.04 w/ Gnome and TeXLive 2014. I include the line PATH=/usr/local/texlive/2014/bin:${PATH} in the Renviron.site file, which now looks like: ## Emacs please make this -*- R -*- ## empty Renviron.site for R on Debian ## ## Copyright (C) 2008 Dirk Eddelbuettel and GPL'ed ## ## see help(Startup) for documentation on ~/.Renviron and Renviron.site # ## Example ~/.Renviron on Unix # R_LIBS=~/R/library # PAGER=/usr/local/bin/less # ## Example .Renviron on

When I include \usepackage{Sweave} in the preamble of a beamer presentation, beamer ignores changes to font, e.g., \usepackage{helvet} . Here is a minimal example: \documentclass[professionalfonts]{beamer} \usepackage[T1]{fontenc} \usepackage{helvet} \usepackage{Sweave} \begin{document} \begin{frame} Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. \end{frame} \end{document} The text is set in computer modern,

Is it possible and how to use a LaTeX math expression in a knitr/Sweave report with kable ? In the example below, $x^2$ is rendered "as is". With xtable , for the example below, I would use the option sanitize.colnames.function = function(x) x of print.xtable . Is there such an option for kable ? \documentclass{article} \usepackage{booktabs} \begin{document} <<>>= library(knitr) dat <- mtcars[1:5,1:5] options(knitr.table.format = "latex") @ <<results='asis'>>= names(dat)[1] <- "$x^2$" kable(dat, booktabs=TRUE, caption="My table") @ \end{document} Yes, use the option escape=FALSE : kable(dat,
