Dear Colleagues,
I've been searching for a post or article or something which
explains why having na.rm=FALSE or na.action=na.fail as the default is a
better choice than TRUE or na.omit.
I understand the basic argument: it does not make sense to average a
nonexistance into an
Not 100% sure what you are looking for, but have a look at the Generalized
Event Count model in the Zelig package. It will also let you fit a Poisson and
other event count models by MLE.

Have you tried
table(row(m), m)
? If there is a chance that m doesn't have
at least 1 of each of c(-1,0,1) then force them
into the table with
table(row(m), factor(m, levels=c(-1,0,1)))

Hi all,
Thanks a lot for your responses. I forgot to mention in my posting that I
also want to try to be as cross-platform as possible (and thus to avoid
relying on external calls to UNIX programs such as grep). I like the idea
from Thomas:
You certainly don't want to use repeated reads from the
Dear all,
I have a dataset where I reduced the dimensionality, and now I have a
response variable with probabilities/proportions between 0 and 1. I wanted
to do a logistic regression on those, but the function glm refuses to do
that with non-integer values in the response. I also tried lrm, but
How can I create probability trees in R? I've searched everywhere I could
and still have no clue. :-/

Some points:

2. Interestingly, if I source() the

My proportions come from a factor analysis on a number of binary variables,

By scaling the obtained scores to 0 and 1, I get weighted averages of the

Is there an R call for launching Notepad.exe from within R?
