[R] contour lines in windows device but neither in pdf nor in postscript

[Patrizio Frederic]

dear Ripley and Diffort,
thank you for the quick reply.
I figured out it was my mistake: I wrote this to the list:

contour(x,x,d2)

in fact my framework I used

contour(x,x,d2,labex=0) # that produced the error

then I learned by myself that if I want to suppress labels I have to use

contour(x,x,d2,drawlabel=F)

and everything works fine now. Thank you again,

Patrizio
