Performance
Hello,
I'm applying an arithmetical function the color (R,G,B) of each
pixel of a figure and it's very slow. This is common?
Other thing, are there some library to make modification in figures, eg,
to alter size?
If not, somebody knows some software that makes this, or either, to
resize figures automatically, therefore I go to need to apply to a bank.
Tks,
Francisco.

Unable to provision VM attaching it directly to a OVS bridge
Reposting from virt-tools mailing list:
Hi!
I'm facing a problem that could be triggered by some lacking
of support from libvirt on Open vSwitch (or could be my mistake).
I have interests in researching on virtual networks and
SDN. To keep things simple, I've decided to use libvirt/virt-tools to
manage VM's since my focus is on the network, instead of using a
full feature system

I have just upgraded from Red Hat Linux 5.2 to version 6.0 (with

Missing functions in package e1071(Win*)
Hi!
After unziping the CRAN file e1071.zip
on my Win95 library directory, I start R and
type
>library(e1071)
After that, help commands of the e1071
functions work (i.e., help(read.pnm), BUT
some functions themselves are not available:
> read.pnm
Error: Object "read.pnm" not found
I've looked at the file library/R/e1071 with
an ascii editor and it seems like the functions

simple questions about R (fwd)
OK, I am forwarding this to the r-help. In the original message
I simply hit reply and I thought I send to ALL r-help list. (apparent not)
also I recieved another piece of mail.....about the RNG in
Splus 4.0 or later indicating it was modified and getting worse.
I only have Splus 3.4 for HP. So I cannot try it.
This makes the idea of using the
pre-generated RN on CDROM more appealing..

You can have multiple vethX interfaces on recent builds -- see netback/loopback.c.
I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.

File opening error after 1020 files opened
Hi,
I am trying to use "read.pnm" from the package "pixmap" to read more
than 10 thousand image files in "mydir".

print(i)
x <- read.pnm(file.list[i])

In the beginning it was fine. But after reading 1020 images or so, the

Pixmap problem
Hi,
I'm having trouble writing .pnm images which I think is due to a problem
with my colour space. The pixmap object seems to be looking for 72 of 8
colours (one per cell?) which doesn't seem healthy...

random number generation
Can a single random number be generated in R? I have an exercise that wants
to simulate coin tosses, and I cannot seem to find a good example of the use
of random number generation in R. Any help?

read.pnm question in R-beta
In R-beta (Masked Marvel), when I do the example from the read.pnm help file, this is what happens:
x <- read.pnm(system.file("pictures/logo.pgm",package="pixmap")[1])
Warning message:
In rep(cellres, length=2): x is NULL so the result will be NULL
In R-2.15.3, it's all right.
Thanks,
