[Env: R 2.12.2, WinXp]In a vignette for the vcdExtra package, I had a text file, tv.dat under data/, that I used in the vignette as <<tv1,results=verbatim>>= tv.data<-read.table(system.file("data","tv.dat",package="vcdExtra")) head(tv.data,5) @ I was told that this now generates a warning for non-Rdata files in R CMD check. But I'm now confused about where to put this and how to use system.file() in the vignette to read it. The R-exts.pdf says The R working directory for all vignette tests in R CMD check is the installed version of the ‘doc’ subdirectory. Make sure all files needed by the vignette (data sets, . . . ) are accessible by either placing them in the ‘inst/doc’ hierarchy of the source package, or using calls to system.file(). So, I moved this file to inst/doc/extdata/tv.dat, and changed the vignette to <<tv1,results=verbatim>>= tv.data<-read.table(system.file("inst","doc","extdata","tv.dat",package="vcdExtra")) head(tv.data,5) @ But I get the error: Error: processing vignette 'vcd-tutorial.Rnw' failed with diagnostics: chunk 23 (label=tv1) Error in read.table(system.file("inst", "doc", "extdata", "tv.dat", package = "vcdExtra")) : no lines available in input How can I fix this?
Everything in the "inst" directory is moved up a level when it is installed. So you shouldn't mention "inst" in its path.
