kernel security issues
...he security alerts for the centos kernel I've the
impression that altought they are fixed fastly there are more alerts
than for the vanilla one of the same version.
Question: Are those alerts mostly specifically centos related or do they
also affect the vanilla sources?

Time of day
Is there a simple way to obtain the time of day in R? I want the time of
day for computational purposes, not for display. I want to be able to
create code like the following:
if (time_of_day >= 22:00 & time_of_day <= 06:00) then X otherwise Y
I realize I could parse a date/time object and extract the time, but
hopefully other people have already done this, or there is a
straightforward

Model parameterization / Factor Levels
Dear R users;
I'm looking for some hint about how to deal with the following situation:
Response = Y
Factor A = levels: 0, 1
Factor B = levels: 0, 1
Factor C = levels: 1,2,3,4
Model: Logistic 3-parms.
where th1~1+A+C, th2~1+C; th3~1
For 'simplicity' (for me) I'm using the SAS contrast parameterization.
The output looks like
Beta p-value
th1.(Intercept) 550

formatting output
Dear R-users
A basic question that I wasn't able to solve: Is it possible to get
the results of the function 'quantile' expressed as data.frame? What
I'm doing is to apply the following code to get the quantiles in a
particular dataset:
tmp<-tapply(data$DEN,list(Age=data$AGE,Sex=data$SEX),quantile)
and then I save this output to HTML using the

calibration/validation sets
Hi;
Does anyone know how to create a calibration and validation set from a particular dataset? I have a dataframe with nearly 20,000 rows! and I would like to select (randomly) a subset from the original dataset (...I found how to do that) to use as calibration set. However, I don't know how to remove this "calibration" set from the original dataframe in order to get my
