[R] v3.0.1 issue

[SOPHIA TSIROPOULOU]

Hi there,

I have recently installed the latest R version 3.0.1, replacing the previous version 2.15.2.

Just as I am running R I get a few warnings about packages that I have previously used.

Below I attach the session info a long with the warnings I am getting.

What does these warnings mean? Is there something I could do to fix the issue?

Thanks a lot for your help.

Sophia
