colinearity?
I'm sorry to all those who are tired of seeing my email appear in need of
help. But, I've never coded in any program before, so this has been a
difficult process for me.
Is there a simple function to test for colinearity in R? I'm running a
logistic regression and a linear regression.
Thanks for the help!

R Reference Card (especially useful for Newbies)
Newbies (and others!) may find the R Reference Card made available by Tom
Short and Rpad at http://www.rpad.org/Rpad/Rpad-refcard.pdf useful. It
categorizes and organizes a bunch of R's (S's) basic, most used functions so
that they can be easily found. For example, paste() is under the "Strings"
heading and expand.grid() is under "Data Creation." For newbies

linear models and colinear variables...
Hi!
I'm having some issues on both conceptual and
technical levels for selecting the right combination
of variables for this model I'm working on. The basic,
all inclusive form looks like
lm(mic ~ B * D * S * U * V * ICU)
Where mic, U, V, and ICU are numeric values and B D
and S are factors with about 16, 16 and 2 levels
respectively. In short, there's a ton of actual

Help with colinearity problem in multiple linear regression
Hello,
For basic linear regression lm() does the job well, for datasets that are
larger than memory biglm() seems to work.
I'm working on a parallel implementation of multiple linear regression for
datasets that are too large for memory.
Currently I am working over least squares:
calculating: t(X) %*% X and t(X) %*% y
separately in parallel on each node
This generates a

Rpad examples having problems with local server
Hi, this is Charlie. I have installed the Rpad on my server (using Fedora
Core 6 with httpd2.24-2, mod_perl 2.0.2-6.1, perl 5.8.8 from RPM). When I
access to the Rpad (through http://localhost/Rpad/basehtml), it shows me the
main page as normal, however, problems occurs when I am testing the
examples. It shows me a long message like:

Rpad and R 2.10.0
I have problems with Rpad and R 2.10.0 (Windows XP and Windows 7,
browser is Firefox)
Just starting Rpad by

Doing the same in R 2.9.2 gives clickable links in the browser.

Tom Short's R cheat sheet
I noticed that there is a newer version of Tom Short's "cheat sheet" than
the version currently posted on CRAN.
Personally I like the newer version, but maybe keeping the old version is
deliberate. Anyway, I was wondering if there's someone that I can notify
that can update the content.

HTML masked (due to Rpad?)
With an older verion of R (I think 2.2.0) and an older version of Rpad I
used to use HTML(go, collapse=false) where go is list of objects returned by
a function and this worked great. Now that I have done some upgrading (to R
2.3.1 and Rpad 1.1.0) its not working right. I also get a warning when I
start R that HTML is masked. And when I do ?HTML R tells me that HTML shows

How to install the server version of rpad
Hi,
How can I install the server version of rpad on a website. I have read
the instructions in http://www.rpad.org/Rpad/ServerNotes.html, but
could not figure out how. Do I have to have something like Apache on
the website? Is there any instructions in addition to those on
http://www.rpad.org/Rpad/.
Thanks,
