You can put arbitrary files into a subdirectory of inst in your package, 
e.g. inst/pngfiles or inst/textfiles.  The subdirectory will be 
installed one level up when your package is installed, so you can't use 
a standard directory name (R, src, etc.), but you can use anything else.

You can find the files from code using system.file().

BTW, questions about package development should be sent to the R-devel
