R help - Mar 2011 - Degree symbol

I have been using both Windows and Linux versions of R so when I have
opened files created in Windows I have found some issues in Linux. One
was that my windows setup allowed me to enter a degree symbol from the
keyboard for labelling axes.
Now I have found that the following expression seems to work on both systems

xlab = expression(paste("Temperature [",degree,"C]")),

(I found this on someone's blog, but I forget who-- thank you whoever you
are).

Now my question is can I set up my Linux (ubuntu) system to recognise
the degree symbol input from the keyboard, or for the sake of
portability should I just go with the solution I have found?

The issue may be that your Linux system is using UTF-8 encodings, while 
your Windows one is using the Windows version of Latin1.  So if you tell 
R that your file is encoded in Latin1, it will likely work.  You can do 
this in the DESCRIPTION file for a package, or the "encoding" argument
to source().

You can probably tell Ubuntu to use Latin1 for everything, but I would 
guess that's a bad idea.
