You haven't said you were using the env argument, have you? If so, I
missed that part. I assumed you were specifying the above as the
Hmmm, former message not quoted, as we ask in the posting guide. Where
is the reproducible example?
Anyway, this won't work under a Windows shell, I believe. At least, I do
not know how to set an env variable and run RCMD INSTALL in a Windows
shell as a one liner - independent of R.
