Offscreen rendering in RGL?
Hi there,
I've written a script for reading 3D simulation data into R, rendering
it using RGL, and then saving the resulting plot using the
snapshot3d() function. The results are fantastic! However, whenever
RGL plots anything it automatically brings the viewing window into
focus. Since I'm producing a large number of plots in a loop, my
machine becomes almost unusable for the

qplot in ggplot2 not working any longer - (what did I do?)
This is the first time that I have tried to update packages with a
tinkered around with .Rprofile. I start R with R --vanilla and it
does not load my .Rprofile, but when I issue the command
update.packages() R downloads the packages as expected, but then seems
to load .Rprofile before compiling the packages sources. What am I
doing wrong?
kindest regards,

rgl: coordinating and saving viewpoints, zoom, scale for multiple images
Context: I have two or more rgl-based views of a given data set, perhaps
fitting different
models, or showing different things across views. I want to be able to
hand-rotate, zoom, scale
one view to something I like, and then show the other views with
matching viewpoints and scaling.
so that one could flip back/forth among graphs and see only the relevant
differences.

.Rprofile interfering with update.packages()

Save rgl plot3d Graph as Image
Dear Users:
I wish to save 3d scatter plots I have generated using the plot3d command in
the rgl package. Any image format such as .tiff would work. Can anyone tell
me how to do this?
Thank you

Replacing several rows of a matrix at once
Hello Folks. This must be a silly question with a (not) obvious (to me)
answer.
Consider this:
tmp <- matrix(1:200, nrow = 20)
vec <- 300:309
tmp[9,] <- vec # replacing one row works fine
p <- c(3, 11, 17)
tmp[p,] <- vec
# replacing multple rows pastes the values down a column and recycles vec.
What I want to do is replace multiple rows simultaneously at once. I

Hi all,
While dat['a1',] and dat['a10',] produce the same results in the

tcltk freezing using MS Windows for R-2.14+
I am the maintainer of a Bioconductor package (affylmGUI) which uses

After considerable testing I have reduced the problem from a few

substitute creates an object which prints incorrectly (PR#9427)
The function "substitute" seems to fail to make a genuine
substitution, although the printed verision seems fine. Here is an
example.

y <- function(x) sin(x + 1)

bnlearn and cpquery
Hi all
I have built a Bayesian network using discrete data using the bnlearn

When I try to run the cpquery function on this data it returns NaN for some
some cases.
Running the cpquery in debug mode for such a case (n=10^5, method="lw")
creates the following output:
