Hmm...is this maybe a bug? Check out this section of install.packages():
localcran <- length(grep("^file:", contriburl)) > 0
if (!localcran) {
if (is.null(destdir)) {
tmpd <- tempfile("Rinstdir")
if (!dir.create(tmpd))
stop("Unable to create temp directory ", tmpd)
}
else tmpd <- destdir
}
foundpkgs <- download.packages(pkgs, destdir = tmpd, available = available,
contriburl = contriburl, method = method)
So if `localcran' is TRUE (which in this case, it is), then `tmpd' never gets defined but is passed to download.packages().
The help pages tells us (correctly):
"If CRAN is local, i.e., the URL starts with "file:", then the packages are not downloaded but used directly."
hence we don't need a destdir in this case, therefore no need to define tmpd.
When I run a traceback() after getting the error from running install.packages(), it fails in download.packages() when trying to create the download directory.
Works for me without any error. Are you sure the path you specified was correct? If you are sure, is this R-1.9.1?
