large fonts on plots

Hi all,

I need to enlarge te fonts used oo R-plots (plots, histograms, ...) in 
labels and titles etc.

I seem to be unable to figure out how to do it.    The problem is that 
the titles of the plots are simply unreadable when I insert them into my 
LaTeX text, since they are relatively small compared to the entire plot.

I am sure it is pretty simple, can anybody give me a hint ?
