New version of benchmark comparing R with other software
Hello,
Thanks to Douglas Bates, there is now a new benchmark suite (version 2.3)
which is compatible with R 1.9.0 and the recent Matrix library (0.8-1 or
above). You find it at http://www.sciviews.org/other/benchmark.htm. It
compares R 1.9.0 under Windows with:
S-PLUS 6.5, Matlab 6.0, O-Matrix 5.6, Octave 2.1.42, Scilab 2.7 and Ox 3.30.
In short, R in its version 1.9.0 and with the new Matrix

barplot() does not draw bars correctly in R 1.9.0 (PR#6776)
Bars are not stacked, but superimposed. This happens even with the first
example of barplot:
tN <- table(Ni <- rpois(100, lambda=5))
r <- barplot(tN, col='gray')

Lazy loading... advices
Hello,
I am looking for more information about lazy loading introduced in R 2.0.0.
Doing
?lazyLoad
I got some and there is a 'see also' section that points to
'makeLazyLoading'... But I cannot reach this page.
My problem is: I recompiled a library that uses a lot of functions from
other libraries (of course I can give details if needed). I load it in my
computer: library(svGUI),

R benchmarking program
Hi All,
I've just rebuild the latest R with the Goto BLAS on our new Intel quad core machines. I did a few basic matrix calculations, and I was very impressed by the performance I saw. I wonder if anyone has a more rigorous benchmarking program for R. I downloaded a old R test/benchmarking program (see below), and this didn't work with the current R, and so I wondered if anyone could

nls, nlrq, and box-cox transformation
Dear r-help members
I posted this message already yesterday, but don't know whether it
reached you since I joined the group only yesterday.
I would like to estimate the boxcox transformed model
(y^t - 1)/t ~ b0 + b1 * x.
Unfortunately, R returns with an error message when I try to
perform this with the call
nls( I((y^t - 1)/t) ~ I(b0 + b1*x),
start = c(t=1,b0=0,b1=0), data = mydataframe)

image recognition in R
I have some images of bugs (insects) with many bugs in each image.
I want to count the number of bugs and to have an estimate of the area
of each one.
I've tried searching for an R package to do so with no success. Is this
a task that I should pursue doing in R or should I restrict myself to
specific image analysis software (e.g. ImageJ)?.
The reason I consider R would be a good choice is

Using tcltk to display jpeg images
Dear R Helpers,
Does anyone know how to use tcltk to display jpeg images? The manual says
that
one must use Tk_PhotoCreateImageFormat to register the jpeg image handler.

(http://support.serv.ch/lang/tcl/img/doc/img-jpeg.html)
says:-

R GUI considerations (was: R, Wine, and multi-threadedness)
Hello,
Following a discussion initiated on r-devel, that mentions SciViews-R
and other GUIs issues for R, I would like to make comments (and would be
happy if these comments would initiate interesting initiatives).
A big, big problem with SciViews-R is that a part of it is written in
Visual Basic 6, a M$$$$ language, not supported any more, buggy, non
transposable to other platforms, etc,

Help with Scviews
Dear all
I would appreciate it if someone could help me to install Scviews.
1) I am running Windows XP Service Pack 3 with 1Gb of memory and 120GB HDrive.
2) R is installed and runs fine
RCommander is installed and seems to run reasonably well. Some issues where it 'bombs' out for no reason.
3) I cannot run (install.packages:"Scviews") from any CRAN site.
4) What I have done
