Processing "vignette" files
Is there any way to process the "vignette" documantation files?
I have been looking at the bioconductor packages and most of them have
*.Rnw files in doc directories. They look like regular TeX but have
sections showing R code that seem to choke TeX.
Thanks,
Andy

Rcmdr active data set
Hi,
This seems a very basic problem, but I cannot seem to find the solution to
it.
I am trying to use Rcmdr on a data frame I created in my current R session.
More specifically, I did
x <- data.frame(matrix(0, ncol=3, nrow=5))
library(Rcmdr)
Now I would like to be able to edit, view and perhaps analyze x, but I
cannot seem to figure out how to make it active. Any hint will be welcome.

RGui Titlebar
In the windows version (RGui), is there a way to set
the text displayed in the titlebar of the R window?
When I have 2 instances of RGui running, it would be helpul
if the titlebar could help to understand which is which.

readline with R-1.4.0
Hi,
I am not sure if this is a bug, so I am posting it here. I also searched
the FAQ file for the readline string and did not find anything about the
behavior below.
I just successfully rsync'ed, compiled and tested R-1.4.0 on my RH 7.2
Linux machine. I encountered one problem though. When running ./configure
I noticed that I was getting errors from the readline library. Although

strange slowness of plot
I just ran into this strange behavior.
y <- rnorm(1000)
x <- seq(0, length=length(y))
plot(x, y, type='l', lty=1) - instantaneous
plot(x, y, type='l', lty=2) - 18s plotting lines + 15s plotting axes
= 33s

histogram question
hist(rbinom(1000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,300))
gives a histogram with "touching bars"
hist(rbinom(100000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,30000))
gives a histogram with space between the bars.
is there a way to control the space betweent he bars easily?

factor always have type integer
typeof applied to a factor always seems to return "integer",
independently of the type of the levels.
This has a strange side effect.
When a variable is "imported" into a data frame,
its type changes.
character variables automatically are converted
to factors when imported into data frames.
Here is an example:

Compiling 1.3.1 under RH Linux
Hi,
I am trying to compile R-1.3.1 under RH-7.2 Linux. I used the old gcc
compiler (kgcc) and the compilation went fine. I can start R and run some
rudimentary tasks with no problem. However, when I did
make check
I got the following error in base-Ex.Rout

small error in regression tests
I just r-sync'ed the r-devel version of R-1.7.0 (2003-03-11), compiled it
under RH-8.0 and ran make check. The reg-tests-2 fails at the very end
with the message stating that "object cement was not found". It looks like
this piece of the regression test is new to version 1.7. The the piece of
code generating the error is:

odesolve check fails
Hi,
I just installed the odesolve package and ran the check command on it. It
failed trying to execute
library(gnlm).
Sure enough, there is no gnlm library on my system and I could not find it
on the CRAN archive either. Am I missing anything obvious or is gnlm some
private library that somehow found its way into the example section of
odesolve?
Thanks in advance,

Statconnector and Excel
Hi,
I'm trying to combine a VBA macro and a R package. I've installed the R-(D)COM and the R-excel interface by Neuwirth. They seem to work both. However I would like to display the r-generated data in an Excel sheet as an array but I don't manage.
Here is an example of my source:

Call RInterface.RRun("library(mdnn)")

new lattice/grid
I just installed R-1.4.0 on my Win2k machine from SetupR.exe. Everything
seems to be fine with the base and recommended packages. However, when I
install the lattice and grid packages they do not seem to work. Everything
I try results in something like this:
Instruction 0x00543f06 refernced memory 0x00000000. The memory cannot
be "read".

Re: Problems with rgl package
I also downloaded the rgl package (after reading recent Uwe Ligges' post)
and installed in on my Win2k Pro sp2 machine. It seems to work with no
problems. I ran most of the examples, including the hist3d one, and all of
them worked fine.
A couple of thoughts. I have administrative priviliges on my machine.
Could this possible make a difference. The rgl library uses OpenGL. Is it

identify in lattice
Does identify work in lattice plots? I tried this in R 1.4.1 (original
release) on my Win2000 machine with lattice 0.4-0 and grid 0.5-1.

New versions of lattice and grid
I just ran package update on my Win2000 R-1.6.1 and it installed new
versions of lattice and grid (0.6-7 and 0.7-3 respectively). Then I ran
demo(lattice) and noticed that the last plot, which is supposed to
illustrate math expression usage, fails in the sense that all expression
are shown literally. For example the title of the plot reads " pi*sum(x,
i=0, n)", the x-axis label is

graph history
Hi everybody.
I was just wondering if this is a bug or I am simply doing something wrong.
Here is what happened:
(1) I typed windows() to get the graph menu bar
(2) I turned record on history menu
(3) I created a couple of plots
(4) I checked with PageUp and PageDown that I can scroll through them
(5) I saved the history to a variable, say, hhh
(6) I dumped hhh to a file called hhh.R

PNG diver problem
Hi,
I am having the following problem and I am not sure if this is bug or I am
missing something obvious.
I have a bunch of R functions that automatically process large data sets.
The processing produces several numerical summaries and several graphs
which are subsequently put in reports. I usually do my processing in R
BATCH mode on a Win2000 machine.
All the graphical functions in my package
