Hello!

Trying to fit a non linear regression model

 modF<-nlsModel(kf~3*alpha*epsilon^P, dat, list(alpha=ALPHA))


I get the error message  "Error in numericDeriv(form[[3]], names(ind), 
env) :
        cannot allocate vector of length 1098922500"....I do not 
uneerstand as each of the above vectors kf,
alpha, epsilon have equal length (31 500) and P is a constant

It is probably a trivial error, but I'm stuck!
 

Thanks

Anne
