Subject: [R-pkg-devel] Trouble installing XML on Windows 7 (64-bit)
In-Reply-To: <15DBC0E2A2B8FA49A2369A499E7651360CA03D04@DFBCV9TWPEXP001.ENT.dfo-mpo.ca>
Those packages were built for R-release. There are no appropriate
windows binaries for R-devel on CRAN currently. You need to
compile/install the source package:
install.packages("XML", type = "source")
