r - How can I include hyperlinks in a table within an Sweave document? -

-

i have data frame containing hyperlinks present clickable links using sweave. know xtable, not sure how use treat contents of data frame latex commands.

one strategy use sanitize.text.function print function in xtable. setting sanitize.text.function = function(x){x} causes print echo contents of data frame later interpretation latex:

\documentclass{article}  \usepackage{hyperref}  \begin{document} \title{example of how include hyperlinks in sweave \texttt{xtable}} \author{david r. lovell} \maketitle  <<load-packages, include=false>>= require(xtable) @  <<read-data, tidy=false>>= hits <- read.table(textconnection( "count,link,title 1031,http://australianbioinformatics.net/jobs,jobs 796,http://australianbioinformatics.net/,home"), stringsasfactors=false, sep=",", header=true) @  <<print-xtable, echo = false, results = 'asis'>>= print(   xtable(     hits,     align="rrll",     caption="top content on \\href{http://australianbioinformatics.net}{australianbioinformatics.net} in may 2014."     ),    include.rownames=false   ) @  <<print-xtable-href, echo = false, results = 'asis'>>= linkedhits <- transform(hits, href=paste("\\href{", link, "}{", title, "}", sep="")) print(   xtable(     subset(linkedhits, select=c(count, href)),     align="rrl",     caption="top content on \\href{http://australianbioinformatics.net}{australianbioinformatics.net} in may 2014,      added hyperlinks."     ),    include.rownames=false,   sanitize.text.function = function(x){x}   )  @  \end{document}
