Hi Pascal,
You are right, I had not considered the idea of setting a negative y limit 
when there were no negative values. I think you can fix this by changing:


negy<-any(height<0,na.rm=TRUE) || ylim[1] < 0

I'll check this later (I'm just going out) and if it doesn't work, I'll send 
another email with something that does.
