[R] Correct Localized Numbers on Plots, related to glibc!

[Prof Brian Ripley]

You need to read ?Sys.setlocale (surely part of the homework the R 
posting guide asked of you).

It is vital that you give the 'at a minimum' information requested in 
the posting guide when asking such questions, and we also absolutely 
need to know what graphics device you are trying to use.

It will if they followed the documentation.
