Please read the help for par(mfrow)! AFAICS this is nothing to do with
boxplot().
In a layout with exactly two rows and columns the base value
of '"cex"' is reduced by a factor of 0.83: if there are three
or more of either rows or columns, the reduction factor is
0.66.
See also the 'consider the alternatives' in that entry.

Hi all!
So far I learned some R but finilizing my plots so they look
publishable seems not to be possible.
I set up some boxplots. Everything works well but when I put more then
two of them in one plot the labels of the axes appear smaller than the
normal font size.
x <- rnorm(30)
y <- rnorm(30)
par(mfrow=c(1,4))
boxplot(x,y, names=c("horray", "hurra"))
mtext("Jubel", side=1, line=2)
In case I take one or two boxplots this does not happen:
par(mfrow=c(1,2))
boxplot(x,y, names=c("horray", "hurra"))
mtext("Jubel", side=1, line=2)
The cex.axis seems not to be changed, as setting it to 1.0 doesn't
change the behaviour. If cex.axis=1.3 in the first example the font
size used by boxplot and by mtext is about the same. But as I use a
function to draw quite some of these plots this "hack" is not a proper
solution.
I couldn't find anything about this behaviour in the documention or
the inet.
Can anybody explain? All hints are appriciated.
Thanks,
S. Merz
