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?

Apparently you have put together the location of the current path and the one of the tempfile which does not make sense.
So very likely a bug in your code. Surprise you do not see it on your end. Best, Uwe Ligges
