Porting let* from Common LISP to R
...ask this question because I sometimes encounter infinite recursion in
testing my code. I think that the problem might come from differences
between the Common LISP and R evaluation models.

Applying variable labels across a data frame
Hi All,
I'm working on a class example that demonstrates one way to deal with
factors and their labels. I create a function called myLabeler and apply
it with lapply. It works on the whole data frame when I subscript it as

Second, how can one implement a link function of the
type f(x) = (1+exp(x)/(1+exp(x)))/2 in R?
Third, can it be also done with gee and/or glmm?
