If the package passes the checks (R CMD check) on your macine, it should
be fine. Some compiler warnings are expected.

I installed RF on Linux OpenSuSe 11.1 and while it did install and did run a model I had
created on Windows correctly, it gave me a lot of "uninitialized" warnings. I
don't know if these are significant and so am a little concerned even though my model
ran. Any thoughts?
Thanks
