R help - Jan 2012 - pretty(range(data$z),10) Error

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)
Zusätzlich: Warnmeldungen:
1: Removed 10000 rows containing missing values (stat_contour). 
2: In min(x) : kein nicht-fehlendes Argument für min; gebe Inf zurück
3: In max(x) : kein nicht-fehlendes Argument für max; gebe -Inf zurück
4: In min(x) : kein nicht-fehlendes Argument für min; gebe Inf zurück
5: In max(x) : kein nicht-fehlendes Argument für max; gebe -Inf zurück
=========================================================================== 
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:
 
segment Qq01 Qq02 Qq02a Qq04 Qq05 Qq07 Qq08 Qq10 Qq11 Qq15 Qq17a
A 7 5 5 5 5 4 5 5 3 7 7
A 5 4 4 3 4 3 4 4 4 5 6
B 3 3 3 3 2 3 4 2 4 3 2
B 6 4 5 3 3 3 4 4 3 6 6
C 3 3 3 3 3 4 2 3 3 4 2
C 2 1 4 3 1 4 1 1 3 4 2
D 5 3 4 3 3 3 4 3 3 6 3
D 5 3 4 2 2 4 4 3 3 4 4
E 3 3 3 2 3 4 4 3 2 3 4
E 7 5 5 5 5 4 4 5 1 7 7
F 6 5 4 3 3 3 4 3 3 6 6
F 5 3 4 3 3 4 4 3 3 4 4
G 4 3 3 3 2 1 3 3 3 4 4
G 6 5 5 5 5 4 5 5 3 7 7
H 6 5 5 4 4 4 5 4 3 5 6
H 7 5 5 5 4 4 5 5 3 7 7
I 6 5 5 4 4 4 5 4 3 6 6
I 6 3 4 2 3 4 4 3 4 6 4
J 5 3 4 1 3 4 4 3 3 5 5
J 4 2 4 3 2 2 3 2 3 4 4
K 4 4 4 2 3 4 4 4 3 5 5
K 6 4 3 3 2 3 4 3 3 6 5
L 6 4 5 3 3 4 5 4 3 6 6
L 3 1 2 2 1 3 3 1 3 4 4
...
About 1.800 cases (more than 100 per segment).
Did anybody experience similar problems?
 
Thanks for all comments,

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.
