[R] Vertical labels on axes overlap

[Tomas Kalibera]

Hello,

when using horizontal labels (default) in plots on x-axis, R by default 
selects a subset of labels to plot so that the labels do not overlap. 
However, when using vertical labels, all labels are always drawn, even 
when they overlap. Is it a bug or do I have to adjust some magic parameter ?

the problem can be shown on these 2 tiny examples:

horizontal labels (default) [OK]:

 > plot(1:100,axes=FALSE)
 > axis(1,at=1:100,labels=rep("aaa",100))

(only a subset of labels is drawn)

vertical labels [THE PROBLEM]:

 > plot(1:100,axes=FALSE)
 > axis(1,at=1:100,labels=rep("aaa",100),las=2)

(all labels are drawn - and they do overlap)

Thanks,

Tomas
