[R] Warped Text in mtext in a Quartz-Window

[Bernhard Pollner]

Hello,

With one procedure, I get a strangely warped text in the mtext-area of a quartz-window, while with an other the text comes out OK - see attached PDF.
(Number of Trials is the x-Axis label, which always comes out OK)

The two procedures differ in the statistics they perform and in the graphics they draw, but the writing of the (different) text in the bottom are of the quartz-window is the same function for both procedures. Only that one time the text comes out correct, the other time it is warped.

The mtext is defined as follows:
mtext(TheTextVariable, side=1, outer=TRUE, adj=0.5, line=0.5, col=TheColor)

R Version 2.11.1 (2010-05-31), OSX 10.6.4

Can someone give me a hint what could cause this unexpected behaviour?

Thanks a lot,
kind regards,
