Dear R users,
I have a response variable in a csv file called "y" and a matrix of
predictor variables in a csv file called "mat". I have used the function
"nls" I have specified the nonlinear relation between these variable.The
code I have witten is called Rprog which begins with the phrase:
L.minor.m1<-nls(Y~a ....etc..
The program when I execute the program, I obtain the following message:
L.minor.m1 file not found.
You find attached Rprog, y.csv and mat.csv.
Can you please help me, it is very important for my phd thesis.
Thanks in advance.
Hammadi.
