Dear Sir,
How I can obtain the predicted values of Y variable with fitting smooth spline
regressions (in GAMs) using R software?
in my research, temperature (X variable) is as smoother and fish catch values
(Y variable) is as response
variable.
I would be grateful if you could help me.
Yours sincerely Parviz

A question such as this should be sent to the R-help@R-project.org mailing
list, but first I would advise you to clarify your question and, most
helpfully, include information on the version of R and of any R packages you
are using. This can be obtained by entering
sessionInfo()
after you have fit your model. You could cut-and-paste the results that are
shown as the result of that statement.
