Dear R-help members,
with the help of one of you the following R-Code was developed. No I have the
(probably simple) problem that I want to increase font size of "text" and
"ylab" names from 1 to 2. Unfortunately I'm not able to adjust the margin so,
that the plot is appers complete (all names readable) on a 8:14 Inch scale
plot.
Some times I get the error message that the margin borders are to big (if I
increase the oldpar value), sometimes nothing happens , I have no clue why. Can
anyone help me?
Thank you
Michi
