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

Hi,
Are there any implementations of stacked RBMs either complete or planned in
R?

PLEASE do read the
?sort.list. That is ultra fast for
integers. Again radix is something Tom added to data.table. The radix
algorithm (see wikipedia) is specifically
designed to sort integers only. We would use Date, but that is stored as
numeric. IDate is the same as Date

o that code as I
didn't test it, but I think it should be possible in 32bit using R 2.12.
Is it an option to just keep it in long format and use a data.table ?
testDate[, somecomplexrfunction(onecolumn, anothercolumn), by=list(V2) ]
Why you you need to reshape from long to wide ?
HT
he rest still applies, and you might have a much easier time than I thought
since you are on 64bit. I was working on the basis of squeezing into 32bit.

vely locks me out of my
computer for the duration of the simulation.
my question is this: can anyone suggest how i might pass the "quiet" command to
the DOS program? is there a way to generally specify this from R? or any
specific recommendations/experience with this package?
riterion =
qnorm(0.95) which would obviously feed the function a different value.
Thanks in advance,
Matthew
