Hi all, 

 

I have a problem with this code... as it generates an error in R. 

 

z<-predict(dat.fit, newdata=grd)

 

I saw a post on  R forum about this ["chfactor.c", line 130: singular matrix in function LDLfactor() ] error and tried pretty much anything I could  read about it and still haven had any luck with it. I have tried with the zerodist() and there are no duplicate point within the dataset..

 

Thanks, m
