I am working on knitr right now, One of the string that I was trying to print has the % symbol. I read up on the TeX manual that to a print the % symbol. TeX should have the string as \% to display the code.
Using the command gsub I tried to do the following:
try = "0% success"
try2 = gsub("%","\%",try,fixed = TRUE)
gsub throws an invalid escape character error
If I do this:
try = "0% success
try2 = gsub("%","\\\\%",try,fixed = TRUE)
knitr will still not be able to print the string
Please suggest me with a way that I can solve my problem
--------EDIT------------------
I want the string in try to displayed as it is in my output PDF I am using this in knitr as \textit{\Sexpr{try}} When the tex file gets created, it believes that the text after percentage is a comment. I am creating an rnw file first and then creating the tex file, after which using texi2pdf to get the pdf file
----EDIT 2 -------------
I am not very good with either knitr or LaTeX
