a problem sourcing a file using chdir=TRUE
Dear R-users,
I used to give commands such as:
> source(file="~/path/to/file.R", chdir=TRUE)
but with the latest v. 2.1.0 it does not seem to work anymore.
I tried to figure out what it was going on and it seems that the string
for which

[1] "character"
is changed to

[1] "file" "connection"

combining mathematical notation and value substitution
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
appear instead of the word `theta'. How can I do so most easily? I don't
understand the

ordering points as vertex of a polygon
Dear R-users,
Suppose I have the following x-y coordinates which give the boundaries of
a polygon:
> x <- c(5,4,5,9,6,6,4,7,10,7,10,4,10)
> y <- c(6,3,2,6,3,7,5,4,4,7, 5,4, 6)
I would like to plot the following graph:
> plot(x,y)
> ord <- c(7,12,2,3,5,8,9,11,13,4,10,6,1)
> polygon(x[ord],y[ord])
How I can obtain the above ordering (in the example an anti-clockwise

Installing RXlisp
Dear R users,
I was trying to install the package RXLisp by Duncan Temple Lang on a MDK
9.1 Linux machine running R 1.8.0 installed from a RPM.
Unfortunately I had a problem loading the shared library into R. Since
I'm a Linux newbie I was not able to solve the problem. Maybe some of
you can help me.
First of all I downloaded the source archive for Xlisp-Stat and
for the RXlisp package.

glm and overdispersion
Hi,
I am performing glm with binomial family and my data show slight
overdispersion (HF<1.5). Nevertheless, in order to take into account for
this heterogeneity though weak, I use F-test rather than Chi-square
(Krackow & Tkadlec, 2001). But surprisingly, outputs of this two tests
are exactly similar. What is the reason and how can I scale the output
by overdispersion ??
Thank you,

glm.poisson.disp versus glm.nb
Dear list,
This is a question about overdispersion and the ML estimates of the
parameters returned by the glm.poisson.disp (L. Scrucca) and glm.nb
(Venables and Ripley) functions. Both appear to assume a negative binomial
distribution for the response variable.

Infinite recursion in S3 methods crashes R on windows (related to PR#8203?)
Hi,
Infinite recursion in S3 methods seem to crash R on Windows 2000 (R
