Hi list,

I tried to use nls to do some nonlinear least square fitting on my data with 
340 observations and 10 variables, but as I called nls() function, I got 
this error message:
Error in qr.qty(QR, resid) : 'qr' and 'y' must have the same number of rows
Then I traced back a little bit into nls() function, the error seemed to 
happen when calling nlsiter() internal function, but I did not find any clue 
calling qr.qty() function in nls.c. I searched around mailing list, there 
were some posts about this message but none of them were clearly solved. I 
wonder if anybody solved this problem? (Bate's example worked, though)
