pretty(range(data$z),10) Error

Hi Mario,

If you're still having problems, I'd suggest sending a small
reproducible example
(https://github.com/hadley/devtools/wiki/Reproducibility) to the
ggplot2 mailing list.

Hello, R-List,
I'm getting error messages when adding geom_density2d() [package ggplot2]:
============================================================================
Fehler in pretty(range(data$z), 10) :
? NA/NaN/Inf in externem Funktionsaufruf (arg 1)
Zus?tzlich: Warnmeldungen:
1: Removed 10000 rows containing missing values (stat_contour).
2: In min(x) : kein nicht-fehlendes Argument f?r min; gebe Inf zur?ck
3: In max(x) : kein nicht-fehlendes Argument f?r max; gebe -Inf zur?ck
4: In min(x) : kein nicht-fehlendes Argument f?r min; gebe Inf zur?ck
5: In max(x) : kein nicht-fehlendes Argument f?r max; gebe -Inf zur?ck
============================================================================

I installed 2.11.1 Patched in the hope to overcome this obstacle but in vain.
I tried reading spss and csv format - no effect.

While this one works:
ggplot(sp2, aes(x=Qq04, y=Qq01)) + geom_point() + facet_wrap(~ segment,ncol=3)
This one fails:
ggplot(sp2, aes(x=Qq04, y=Qq01)) + geom_point() + facet_wrap(~ segment,ncol=3) + geom_density2d()

But it only fails for 2 out of 10 x-variables, although they do not differ in structure.
Data structure looks like this:

About 1.800 cases (more than 100 per segment).
Did anybody experience similar problems?

Thanks for all comments,
