Dear list subscriber, suppose, I do have a minimal Sweave file 'test.Rnw': \documentclass{article} \begin{document} <<printx>>= x @ \end{document}
Within R, I define the following function: f <- function(x){ Sweave("test.Rnw") } The call: f(x = 1:10) results in the following error message: > f(x = 1:10) Writing to file test.tex Processing code chunks ... 1 : echo term verbatim (label=printx) Error: chunk 1 (label=printx) Error in eval(expr, envir, enclos) : object 'x' not found In principle, I could assign x to the global environment and then the Sweave file will be processed correctly: > f2 <- function(x){ + attach(list(x = x)) + Sweave("test.Rnw") + } > f2(x = 1:10) Writing to file test.tex Processing code chunks ... 1 : echo term verbatim (label=printx) You can now run LaTeX on 'test.tex' > Kind of a dum question, but how could it be achieved that Sweave recognizes the objects within this function call?
