Hi all,

I'm modeling using lme in the nlme package. qqnorm makes plots just find,
but when I try to add a line with qqline, I get the following error:
"Error in sort.list(x, partial = unique(c(lo, hi))) :
  'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?"

For example
> modelincr10<-lme(lruin~can.pos.num, data=rwushi30, random=(~1|
site/transect/plot),na.action=na.omit)
> summary(modelincr10)
> qqnorm(modelincr10, main="qqnorm res10")
> qqline(modelincr10)
Error in sort.list(x, partial = unique(c(lo, hi))) :
  'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?

Any help much appreciated.

Ben
