I do have an Rmd where I would like to conditionally evaluate the second part.
So far I am working with : ```{r} if(length(specLibrary@ionlibrary) ==0){ library(knitr) opts_chunk$set(eval=FALSE, message=FALSE, echo=FALSE) } ``` Which disables the evaluation of subsequent chunks. However my RMD file contains also these kind of snippets : `r ` How do I disable them? regards -- Witold Eryk Wolski ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
