Hello,
I apologize that this is off-topic. I am seeking information on
perception of graphical data, in an effort to improve the plots I
produce. Would anyone point me to literature reviews in this area? (Or
keywords to try on google?) Is this located somewhere near cognitive
science,
This is to submit a commented example function for use in the data
argument to the bigglm(biglm) function, when you want to read the data
from a file (instead of a URL), or rescale or modify the data before
fitting the model. In the hope that this may be of help to someone out
there.

Dear Prof. Ripley,
Many thanks for your reply, especially during the holiday season!

You seem to believe a multinomial logistic regression is a GLM: it is
not.
With one line, you've struck the heart of one of my problems.
As a follow-up
I would like to perform a multinomial logistic regression on a large
data set, but do not know how. I've only thought of a few possibilities
and write to seek advice and guidance on them or deepening or expanding
my search.
On smaller data sets, I have successfully loaded the data and issued
OK, well, seeing Thomas Lumley's post earlier today, I figured out the

In R, is there an automatic variable that stores the results of the most
recent command or commands? (I am thinking of a behavior like
Mathematica's % result-history substitution syntax.)
(I am using R 2.3.1 on Linux and R 2.3.1 on Windows XP.)
This is a pretty basic question, so I tried to
