functions not found after installing DBI/RDBI packages
Hi,
I would like to be able to use R with a connection to a PostgreSQL database. I am using R 2.0.1 on windows XP. I have tried installing both the DBI and rDBI packages (which is better?) but in either case I run into the same problem - when i try to use either the dbDriver or dbConnect functions i'm told the function couldn't be found. Seems like the packages aren't installing

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),

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

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.
The
"ActiveTcl User Guide"
(http://support.serv.ch/lang/tcl/img/doc/img-jpeg.html)
says:-
"The package img::jpeg is a sub-package of Img. It can be loaded as a part
of the complete
Img support, via package require

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

r <- barplot(tN, col='gray')

I already posted on the Crimson Editor forum but it seems to be VERY few
R-users there....

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

Task View for ecology/environmental science
Having just discovered "Task Views" I see there isn't one for
ecology/environmental science.
I don't have the expertise to help with this, but I think it would be
a very useful addition if there was any person (s) on the list willing
to help create such a Task View.
I am sure the maintainers of the Task Views will pick up on any
responses to this post from volunteers.

R for Windows server
Hi,
I need to run a burdensome simulation. I'm using a Dell PowerEdge 2850, 3.8 Ghz CPU, 2 Gb RAM, Windows server 2003, 32 bit. The task manager indicates that Rgui.exe is using 25% of the CPU speed. There is no other process that is slowing down R.
Does anyone know if it's a limitation of R? If so, can I set up the program for the CPU usage like I do for the memory usage? Is there a
