[R] install package in Mac

[Rhett Eckstein]

Hi, all

I have problem about installing package (built in Windows) in Mac.

In the R for MacOS X FAQ, it mentioned that Mac required the

prebuilt package named as XXX.tgz.   However, the package built

under Windows named as XXX.zip.  So how should I do to let the

package (built in Windows) to install in Mac.

Thanks in advance !!
