compared scale values between placebo and drug for all time conditions and
scales, which sums up to

Migrate CentOS 3 to 4 to 5?
Hi,
After the previous debacle with PHP and MySQL it has been decided
that we think about an upgrade from CentOS 3 to 5, since that would
solve our problem, if successful. I tried finding information on how
to best attempt this, but thanks to a plethora of contradictory
information my head is now spinning with a few rpm (rounds per minute).
The situation is as follows: Remote box at our

I'm struggling to find the best (set of?) function(s) to do repeated

How to import timestamps from emails into R
I am analysing occurrences of a phenomenon by time, and each of these

Putting all independent variables in one variable so performing many similar tests is more convenient
I want to do something like this.
avo(q~a+b+c+d+e+f+g+h+i+j+k+l)
avo(r~a+b+c+d+e+f+g+h+i+j+k+l)
avo(s~a+b+c+d+e+f+g+h+i+j+k+l)
(There's likely a better way to do this actually, but I think this'll work.)
How do I define e=a+b+c+d+e+f+g+h+i+j+k+l such that the following works?

piecewise linear regression
We sent questionnaires to lots of folks. The questionnaires
differed in word count (wc). For each questionnaire, I know wc
and whether the questionnaire was returned or not (status). It
looks like there is a fixed rate of return when wc is below a
break point, and the rate of return falls off linearly after
that.
