In "pamr", I found that they wrote their own error handler function and
set as .Options$error. I set .Options$error back to NULL, problem solved.

I thought about other cases but I have to dissagree with you. For

Let's say that -b- is a result of comparison not of -a- to something

Assuming all the data are in a subdirectory called "Data" and all the files
have the '.txt' extension, you could do something like.

To paraphrase a recent reply by the inimitable Deepayan Sarkar, take a look
at trellis.par.get('layout.heights'). Playing with some of those arguments
(especially the "padding" ones) may get you what you want.

R-users,
I'm having some trouble getting .glm and glm.nb to run a polynomial.
I've used x*x and x^2 and neither works. I've checked out the archives
and they refer to an archive that's no longer working.
I've seen that they use poly() but I'm following up my analysis with
cv.glm so I'd prefer
I think you want:

This is shown as an example on pg 50 of "An Introduction to R"
