I think that I have encountered a bug in the function "available.packages" when
using a local repository (file://
) on Windows.
Version information:
platform i386-pc-mingw32
arch i386
os mingw32
system i386, mingw32
status
major 2
minor 5.1
year 2007

svn rev 42083
language R
version.string R version 2.5.1 (2007-06-27)
I have made a copy of the CRAN "/bin/windows/contrib/2.5" directory in the
"D:/CRAN" folder on my machine.
When I issue the command:
available.packages(contrib.url("file://D:/CRAN"))
I get the follwoing message:
Error in gzfile(file, "r") : unable to open connection
In addition: Warning message:
cannot open compressed file ':/CRAN/bin/windows/contrib/2.5/PACKAGES' in:
gzfile(file, "r")
Looking at the source code, I've spotted the following lines which seem to cause
trouble:
if (.Platform$OS.type == "windows") {
if (length(grep("[A-Za-z]:", tmpf)))
tmpf <- substring(tmpf, 2)
}
Deleting them, the function works OK.
