Hi,
is the announced solution for the GO 1.7.0 installation already
publicly available?
I am running into the same trouble as described in below, using
2.0.1 under Ubuntu Hoary.
Thanks,

Dear R users,
in some circumstances, try() shows a strange behaviour,
when the pixmap package is loaded.
The following piece of code works as expected, if it is
either sourced in an interactive session or invoked via
R CMD BATCH (the try-error is printed).
However, if i invoke R using ``R --van
Dear R Gurus,
for some purpose i have to use a socket connection, where i have to read
and write both text and binary data (each binary data package will be
preceeded by a header line).
When experimenting, i encountered some problems (with R-2.0.1 under
different Linuxes (SuSE and Gentoo)).

Dear R users,
can anybody explain the reason, why the first piece of code
below gives a parsing error, while the other two variations
work?
# Gives a parsing error
x <- 1
if (x < 0)
{
y <- 1
}
else # Error occurs at this line
{
y <- -1
}
# This works
x <- 1
{
if (x < 0)

disappear.
and the model gives reasonable results in my first simulations
with normally distributed study effects.

Dear R gurus,
for a simulation concerning study effects and historical controls
in survival analysis, i would like to experiment with a gaussian
frailty model.
The simulated scenario consists of a randomized trial
(treatment and placebo) and historical controls (only placebo).
So the simulated data
Dear R Gurus,
i recently noticed that R does sloppy argument checking for named
arguments, if the argument contains a dot.
Example:
> f <- function(foo.bar=0) { print(foo.bar) }
> f(foo=1)
[1] 1
I guess, this should be considered as a bug.
Anyway, the consequence is that bugs caused by typing error
Hi,
when calculating the Cox model for a factor with n levels
(using treatment contrasts), i noticed that the off diagonal elements
of the estimated covariance matrix are always nearly (but not exactly)
equal.
On the one hand, this is plausible to me: If i could obtain estimates
x_i, 1<=i<=n, for t
s rather than the typical ~2 second R startup time.
Thanks for any tips.

Hi,
if found that the easiest way for me doing CGI with R was
using the RSPerl package. So i could do all the CGI related things
in Perl and call R functions from Perl to do the statistics.
You can get RSPerl from http://www.omegahat.org.
If loading the data each time gives a performance problem,

did anybody succeed in building R on SuSE Linux 9.1?

perhaps this is a stupid question, but i need some help about
Helmert contrasts in the Cox model.
I have a survival data frame with an unordered factor `group'

Calculating the Cox model with Helmert contrasts, i expected that
the first coefficient would be the same as if i
Dear R-Gurus,
is it possible, to define variables, which are only
visible to functions belonging to a certain package?
(For a certain package i would like to have something
similar to static variables in C, which are only visible
to functions defined in the same source file.)
