I have a program which is being feed a formula. One of the terms in
the formula is going to be r(variablename). r just returns the
original variable.
r <- function(x) x
The formula is something like
rglm(y ~ x + r(Subject))
What I want to do is get access to the variable Subject directly. Can
anyone give me any suggestions for doing this?
Thanks
Murray Keir
