linear regression

The model is:-
fm1 <- lm(TS.CM ~ AGE + SEX + HFE.Y.01 + TFC2B.01 + HFE.Y.01*TFC2B.01, data
= IRONresults, subset = DIAG2.1D == 0)
summary (fm1)
TS.CM is a continuous variable (%s), sex is coded 0 = women, 1 = men,
DIAG2.1D is coded 0 = non-demented, 1 = ALzheimer's disease and the genes,
HFE.Y.01 & TFC2B.01, are coded 0 = non-carrier and 1 = carrier
I've tried recoding the data to use 1 & 2, instead of 0 & 1, and I've

Positions at GMI, Dublin, Ireland
Dear mailing list,
Genomics Medicine Ireland is opening new positions for our bioinformatics team. The team will analyse the ?omics data produced at GMI, which currently includes disease cohorts such as IBD, Multiple sclerosis, Alzheimer's, rare diseases, cancer and recently we have opened programs in diabetes and asthma. Our work will also focus on ancestry related topics, namely how population genetics can increase the power of disease analysis.
We are building a team of cognitively diverse people, that will feed off each o...

compilers for R on AMD64
Dear R-devel,
A while ago Prof. Ripley had mentioned that g77 on AMD64 isn't the greatest,
and the Salford Fortran is likely to be better. My question is, has anyone
tried compiling R with Salford compilers (or other commercial compilers)?
If so, do they offer performance advantages over GCC?
TIA for any info.
Best,
Andy

A Tribute to my Great Grandmother (Off Topic)
...uch you want to cry, or to fight, or
to curse, or to disappear, remember that laughter is better than
fighting, crying, and being sad. Laughter is what will get you
through. This is what Grandma Ethel taught everyone she touched. She
did not fight growing old. Maybe it had to do with her having
Alzheimer's. But she didn't the whole time. She only had it at the
end. When she knew she was growing older, she accepted it. She
laughed about it. She joked about it. And she didn't fight when it
was her time. She was ready. She was, and still is, a shining star.

DNS problem
Hello,
Today I restarted the firewall machine during an outage of the ADSL line
overhere. At the boot Shorewall did not start but stopped during start.
The problem was that the ADSL line was down so no DNS server available
to resolve hostnames. I have a hostname in "blacklist" file and
therefore shorewall did not start. Is this problem solvable without
putting an IP address in the
