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?
There is no lme methof for qqline.
Have you read the help page for the qqnorm.lme function?
?qqnorm.lme
I am guessing that you did not realize it was a completely different
function that qqnorm.default.
