Problems with paste and blank
Hi there,
I've got the following problem under Windows XP, R 2.5.1:
When I'm pasting some objects:
Stadtwerksname<-"Mannheim"
Laufwerk<-"C:\\"
paste(Laufwerk,Stadtwerksname,".csv")
I get the result:
[1] "C:\\ Mannheim .csv"
The problem's are the superfluous gaps/blanks between the three parts.
Is there a way to get rid off this

Adressing multiple cores (CPUs)
Dear all,
I'm sitting here just in front of my new PC@work and wonder about the following question:
* How can I adress multiple CPUs (cores) out of R to speed up the simulations I run?
* What are the prerequisites to do so?
Maybe anyone could give me a hint where to start reading?
Regards,
Thomas
P.S.: I searched the R-archive to find an answer but did find none.

The quadprog package
Hi everybody,
I'm using Windows XP Prof, R 2.5.1 and a Pentium 4 Processor.
Now, I want to solve a quadratic optimization program (Portfolio Selection) with the quadprog package
I want to minimize (\omega'%*%\Sigma%*%\omega)
Subject to
(1) \iota' %*% \omega = 1 (full investment)
(2) R'%*%\omega = \mu (predefined expectation value)
(3) \omega \ge 0 (no short sales).

I did my homework and read the posting guideline :-)

[PATCH] v2v: bootloaders: handle no default grubby kernel (RHBZ#1519204)
When using grubby to get the default kernel of a guest, do not fail
with a bogus error like:
virt-v2v: error: libguestfs error: statns: statns_stub: path must start
with a / character
in case there is no default kernel that can be determined (e.g. because
of a bogus configuration).

Raster images and saving with original pixel dimensions in tiff, jpeg, or png perferablly.
Hello R-Help,
I want to be able to read in a raster image, plot it with grid.raster
or rasterImage and save the image with one pixel per a pixel element
from my array. Saved preferably in a common image format.
The real goal of my question is to eventually read in images with text
on them, manipulate them with my controlled functions, save them
without changing the image dimensions, and perform

jpeg and margin text
Hi guys,
I use R 2.6.2 and Windows XP.
I’ve got the following question: I wrote a lot of text into the margin of a
plot. When I use the “jpeg”-function, only a little part of the margin text
is displayed in the final jpeg? Any ideas to change it?

IOMMU and kernel (solved?)
I think i might have solve it.
For some reason grub2-mkconfig doesnt work. (Have no idea why)
I manage to solve it with grubby.
sudo grubby --args="intel_iommu=on" --update-kernel=ALL
For some reason it works. I dont know if it works if my kernel gets
upgraded.

Request for assistance: grubby
I wonder if there would be anyone who would be willing to add extlinux
support to RedHat's grubby program. From the looks of it, they already
have grub, lilo, zipl, elilo, yaboot, and silo support, so I can't
imagine it's that complex.

to modify a vector
Hi All.
I am quite a newbie to R.
This is a basic question.
I like to modify elements of a vector.
For Example:
a1 <- c(1,2,3,4,3,5)
TThe following program sentence does not work but the intention is;
if (a1==3) a1*3 .
3 in the vector should be changed to 9, and
the resulted vector is (1,2,9,4,9,5).
How can I get the result?
Thanks in advance for help.

Error occurs when build kernel 3.2.0
Hi all,
Please let me know if this is not the right place to ask this question.
I was trying to compile and build kernel 3.2.0, by following <Linux
Administration - A Beginner's Guide> written by Wale Soyinka.
Error occurs after running the following command:
# new-kernel-pkg -v --mkinitrd --depmod --install 3.2.0-custom
initrdfile is /boot/initrd-3.2.0-custom.img

new-kernel-pkg needs to be made Xen-aware
I ran "yum update" the other day on my dom0 and let it pull a new kernel.
The RPM install scriptlet runs /sbin/new-kernel-pkg (part of the grubby
package) to update grub.conf. It writes a new record to boot the Linux
kernel instead of Xen. It would be nice if it noticed that it was running
inside Xen and wrote a suitable record for that.

jpeg and pixels
Dear R People:
When using the jpeg function for plotting,
is there a way to set the size in inches, please?
There is an option for width and height in pixels, but
not inches.
Any suggestions would be welcome!!!!!

Thanks in advance!
