Hi I have this problem and do not know how to solve it, I'm new to R

R version 2.15.0 (2012-03-30)

That is a very old version of R: the posting guide asked you to update before posting.

Copyright (C) 2012 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-unknown-linux-gnu (64-bit)

Which is not very specific. The posting guide asks for sesssionInfo(): on a current version of R that would tell which Linux distro.


x11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 1 at size 16 could 
not be loaded                                     

You read the manual, the current version of which is at http://cran.r-project.org/doc/manuals/r-release/R-admin.html#Useful-libraries-and-programs , starting 'For the best font experience with these devices you need suitable fonts installed '.

You should also check

capabilities('cairo')

if that is false (as I suspect), read the parts about cairo support and reinstall R with cairo support.
