Can you help me interpret the output I get with polymars?
I'd like to find a regression model to predict 2 dependent variables (then
called Y1 and Y2) with 2 independent variables (then called X1 and X2).
Here is the output:
polymars(responses = data[, 13:14], predictors = data[, 2:3])

If you use par(new=TRUE), you are overlaying one graph on top of the
other. In which case, make sure your xlim and ylim are correctly set.
Another way is to split the plotting window. For example
par(mfrow=c(2,3))
for(i in 1:6) hist( rnorm(100), main=paste("Histogram", i))
See help("par")

Regarding just the date and time classes part of your question, an
article in R News 4/1 discusses that.

1. That's _package_, not _library_.
2. See the `trace' option in ?nnet.

R has functions for doing those: sort(), merge(), aggregate(), and t(),
respectively.

Hi. Another, slightly more updated, link to the same info is:

I whole-heartedly endorse Prof. Ripley's suggestion to write down
the log(likelihood) and use optim; I've done that many times with
seemingly good results. For confidence intervals, the best procedure is
to use 2*log(likelihood ratio) being approximately chi-square. If you
are estimatin
1. Read the R Data Import/Export manual.
2. Check the R-help archive, as this question has been asked and answered
many times.

I managed to parse more complex XML files as well. The trick was to
manually determine the position of the child nodes of interest, after
which they can be parsed in a loop. For example:

Your subject line is not clear to me: Stata appears to fit a negative
binomial model, the point being that it is not a glm as fitted by glm.nb.
