Loading required package: grt Failed with error: ??'grt' is not a valid installed package? Is there any pitfall between platforms? And anywhere I could check more detailed error message.
How did you install it in Windows? If you just copied it from the Linux install directory, or if its in a shared directory, it probably wont work. You need to do a proper R CMD INSTALL on Windows, and for that you'll need the assorted dev tools for building R packages on Windows. Barry
