I think that this should work in gam(), but in any case a fix is to put
the subset variable into the data frame. The formula interface works best
this way. In your example you could add idx=1:100 to the data frame and
then use subset=idx %in% 1:10

Hi,
I have a function, callGam, that fits a gam model to a subset of a dataframe. The
argument to callGam is a formula, the subset is determined inside the function itself.
My naïve approach generates and error, see below. I guess this is because 'idx' is
loocked up in the environment of 'formu
