A data file that I’d like to use in my “oce” package is quite large, and
compresses well, so I thought of putting a compressed version into
inst/extdata. I want my documentation to show how to uncompress the file,
partly because these files tend to compress so well that I think users might
like to store them in gzipped form.
Naturally, I want to test my code using R-devel in addition to the ‘release’
version that I have on my box. Since I’ve never been able to get R-devel
installed properly on OSX, I thought of submitting to win-builder. I got errors
as below my signature line. What I don’t understand is the “Invalid argument”,
which seems to be different from the “No such file or directory” that I would
expect to get if there were no file. Any ideas on how to proceed?
