On page 11 of the Extensions manual it says that "R CMD build will automatically create PDF versions of the vignettes for distribution" however, I have not been successful on Windows 2.0.1 beta. I tried creating a simple package by entering the code in the ?package.skeleton example then adding the Rnw file from the utils package to AnExample\inst\doc but when I ran R CMD build it did not seem to create a tex or pdf file. What am I doing wrong? ...
