Error installing RCurl and XML packages on Windows

Question

I am trying to install the RCurl and XML packages and getting an error on Windows. I have tried R 2.15.0 and 2.15.1, cran.r-project.org and www.omegahat.org/R, and binary and source. Any suggestions? Thanks.

你有 cygwin 问题，所以你可能没有 RTools。
