write.table / read.table would be another option but I'm not sure if R
can guess the factor/char/numeric-type correctly when reading the table.
So, is there any way in drop the unused factor levels from *all* factors
of a data frame without import/export ?
Thanks in advance,
Hilmar

factors (cex) I would like to know how R scales axis font sizes internally.
Could someone point me to the method/file in the R-source code (R 2.1.1)
where this scaling is done ?
Thanks,
