Hi R users:
Does any one knows about a R library for deal with
intervention/impact analysis in time series (eg. Box-Tiao et. al. theory?).
Thank you for your help

another possibility would be to load CygWin/XFree86 on your laptop (which

I am trying to model counts data from three different sites where the number of zeros

It certainly can, using message passing libraries or sockets. While
it isn't technically "one session", it's awfully similar to that, for
the user.

I uploaded version 0.3 of the shapefiles package to CRAN earlier today.
Version 0.2 had a bug that omitted the decimal precision in numeric fields
so some programs (such as ArcGIS) would not parse the fields correctly. I

Overall performance depends on a few other things besides CPU clock speed
(e.g., RAM speed and size, cache size, disk speed, etc.) Unless your code
is spending great majority of the time in the CPU, you should not expect
speed-up to be equal to ratio of clock speeds. (Also, as Prof. Ripley

Did you read ?postscript ? You want an encapsulated PS (EPS) file to

I have recently "printed" in R to a postscript file. I'm working on a SSH

And then the default creates a file called Rplots.ps which I can ftp to my

If you can solve the problem for fixed rho = (va/ve) using gls, then
you can call gls for many values of rho, plot the log(likelihood)
contours vs. rho, construct confidence intervals, etc. You may even be
able to write a function to return (-2)*log(likelihood) for a fixed rho
and then use

High-level control of axes in xyplot is implemented by the scales
argument to xyplot. You can include components 'at' and 'labels' in
a list given as the scales argument. See ?xyplot.
