Dear People,
I need to make a label which both contains math notation as well as
substitutes a value for an object. In the following label, len and theta
are one dim variables, and I am substituting their values appropriately.
This label looks fine except that I want the greek symbol for theta to
Hi all,
I am trying to model (continuous) spatial variation in a response variable
as a function of one or more of several explanatory variables. I am
principally interested in obtaining some measure of the relative
"importance" of the explanatory variables. I have found several R
libraries

Thanx to all who responded to my plea for help. You were right, I did not
have the Path environment set properly for the tools package. I get a
little further now, but still get an error message.
My Cmd Window looks like this:

I'd like to understand better how ordered and non-ordered factors are
treated differently when included as explanatory variables in statistical
models. Also, it appears as though glm [family=binomial] (base) treats
ordered factors differently than lrm (design). For example, when fitting

Hello,
I have a simulated data structure in which students are nested within

Thank you both for pointing out that this is a lattice
plot (ie, R's version of Trellis graphics) and therefore
needs something other than par().
I was able to use IE6.0 to search for "trellis" and
find the relevant commands (after using help.start(),
of course). This brings up another question:
I generated a PDF output file of 10 plots. When I try to view it with
Adobe reader (R4 & R5), it will lockup the reader (it is consuming 100% of
the CPU) after presenting the 4th plot. I can generate the plots just fine
in Windows and as a postscript file reading it with GSview.

A solution is at hand using the 'irts' (irreglar time-series)

If your raw data is in a csv file, you could proceed as follows:
mydata <- read.csv(filename,header=TRUE)
basedate <- as.POSIXct(strptime("2003-01-01 00:00:00",format="%Y-%m-%d %X"))
