Hi, When a package's documentation contains \Sexpr{}, R CMD build will build the manual to PDF. I wonder if the full LaTeX log could be suppressed in this case. Currently it looks like this: $ R CMD build foo * checking for file ?foo/DESCRIPTION? ... OK * preparing ?foo?: * checking DESCRIPTION meta-information ... OK * installing the package to process help pages * building the PDF package manual Hmm ... looks like a package Converting Rd files to LaTeX ...... Creating pdf output from LaTeX ...
