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

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
plot(x, y, type='l', lty=3) - 76s ,, + 75s

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.

coefficient of determination on a nls regression
Antonio,
For linear regression we have the following identity
total SS = regression SS + residual SS (*)
where total SS is the sum of squares of observations around their mean,
i.e.
total SS = (n-1)*var(y)
and residual SS is given by the deviance function.
R-squared is defined as
R^2 = regression SS/ total SS = 1 - residual SS/total SS.
You can use this last formula

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

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:

R as a library
I would like to write a stand-alone application (in C) using R's
statistical and graphical capabilities. To make it more challenging I
would have to do it using Windows 2000 platform. I seem to remember that R
can be compiled into a library of subroutines and linked to an external
program. Is this true or is my memory playing tricks on me? I scanned the
FAQs and the "extensions"

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
(7) I quit

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.

I get a change of cursor after the data points and the LS line are plotted

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,
Andy

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

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

data for Rwave package
Hi,
I just installed the new Rwave package. On the Win2000 platform it will
not find its data files (it does fine under Linux).
Here is what I do:
(1) library(Rwave)
(2) data() - this correctly reports all the data sets
available
(3) data(HOWAREYOU) - this fails on Win2000 machine with the
following message
Error in file(file, "r") : cannot open file

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

R help search engine
I recently "discovered" how useful the search engine & keywords portion of
R help can be. I often remember that I could do certain things in R but do
not quite remember the right commands. The keywords by topic section of
the search engine is particularly useful for that. It incorporates
information from installed packages which makes it even more useful.
I just ran into the

RODBC under Windows
Hi,
I have been just playing with the ODBC connectivity under Windows. I have
never done this before and I thought I would go through some examples in
the "Data Import/Export" manual and learn how to setup data connections
while doing that. I ran into a small problem and I am not sure if this is
something I am doing wrong or a bug or, perhaps, a feature of the RODBC
package.
Here is
