Hi,
I've got the R library mgcv for GAM written by Simon Wood which works well

Has anyone ported the S+ GAM library to R?

In a logistic regression model, fitted probabilities make
sense for individual cases (rows in the data set), as well
as for future cases (predictions) for which no outcome
(success or failure) has been observed yet. Fitted
probabilities are calculated from the matrix formula:

I finally figured out the problem. I went ahead and installed Perl 5.8 but
that didn't do it. The problem was that an existing program's directory was
earlier in the PATH and so one (or more) of the components of the Rcmd
INSTALL was an older version. It wasn't zip since I renamed the old zip.

Then, if it gets to the top (.GlobalEnv) it also looks through the list

1) Why are you using multinom when this is not a multinomial logistic
regression? You could just use a binomial glm.
2) The second argument to predict() is `newdata'. `sample' is an R
function, so what did you mean to have there? I think the predictions
should be a named vector if `sample'

Hi R-experts!
Every once in a while I need to convert a factor to a vector of numeric
values. as.numeric(myfactor) of course returns a nice numeric vector of
the indexes of the levels which is usually not what I had in mind:
v - c(25, 3.78, 16.5, 37, 109)
f - factor(v)
