Windows guest eats as many CPU as available
Hello,
I run Debian on my Laptop Lenovo X60s (with VT).
I've created a Windows-XP as well as a Windows-Vista guest on it.
Both, XP as well as Vista, eats as many CPU as available.
Therefore the CPU always has high load and will never reduce cpu-frequenz or
ventilator.
Did this works as designed or should I modify something?
Thanks in advance
Matthias

how to plot a nice legend?
i'd like to plot a legend in my diagram. The diagram will be included
in a TikZ LaTeX document later.
I tried the legend() function, but
- it can not find a good place it self where the legend fits
and playing around with coordinates and scaling consumes a lot time
- standard settings for the text need adjustment
(linespacing is quite large and so on)
Is there an alternative to

automatic SI prefixes as ticklabels on axis
i want to plot values with frequency on a logarithmic x axis.
similar to this example that i found in the web:
http://www.usspeaker.com/jensen%20p15n-graph.gif
I would like to convert long numbers to si prefix notation
like in the example
(200000 to 200k, 35000000 to 3.5 M)
Of course i could create labels by hand, but
i have many files so i need some automatic function.
Has anyone done that

How to include files in .R?
Hi,
may be its a very simple question, but i did not find any documentation
about a 'include' command or something like this.
I have to set many constants in my R-files and want to move all these to
one file, so that i can reuse it in all other R-files.
Something like
include("~/R/myconstants.R")
kind regards,

read data into list of matrix
Hi
i have a list of many files and want to load them into a list of tables, that
can be adressed with a variable 'i'.
something like
files = c("0125um","2000um","2200um","2500um","2700um")
for (i in 1:5)
{
fp[i] <- read.table( files[i] )
}
but this does not work of course.
Has anyone a good hint?
Thank you,

howto import .xls and .ods
Hi,
i want to import data from .ods and .xls files in R on a linux system.
Seems it was a faq in the past, but i found only solutions for Windows.
Is there a handy solution for linux? The best would be something like
mytab <-read.ods(...)
Any hints? Thanks a lot for reading so far,

Hi,
i want to make my plots look uniform in LaTeX documents.
- usage of the same font on axes and in legend like LaTeX uses
(for example "Computer Modern")
- put real LaTeX formulas on the axes
Have you any hints how i can achieve that?
I had no luck two years ago, but i want to try it again now.

How to rotate axis labels? 2009

while searching for a solution i found many solutions in the internet.
But the postings seemed to be many years old and the workaround was a
dirty hack like this:

Now its the year 2009 and there might have been some improvement...
Does anyone know a nice and easy way to turn labels on the y axis in the

par.plot() for repeated measurements
Hello,
I am using the package gamlss in R to plot repeated measurements. The
command I am using is par.plot(). It works great except one thing about the
label of the axises. I tried to label both x and y axises using ylab and
xlab options. But the plot only gives variable variables. The labels did not
show up. Below is the code I used. Any comments are appreciated! Thanks.

adjust font in ggplot2 to LaTeX document
Hi,
how can i adjust the font in a ggplot2 qplot so that it will look
similar to the LaTeX font?
Computer Modern Sans Serif in the same size would be nice.
My output device is
ggsave(filename="test.pdf", width=5.5, height=3, dpi=300)
and i will include the graphic with 5.5 inch in LaTeX.
I found some pages about that topic but all solutions that i found have
been very complicate

fit data to y~A+B*sin(C*x)
I want to fit discrete data that was measured on a wavegenerator.
In this minimal example i generate some artificial data:

testsin <- testsin+ rnorm(length(testsin), sd = 0.01) #add noise
mydata <- list(X=1:100, Y=testsin) # generate mydata object
nlmod <- nls(X ~ A+B*sin(C* Y), data=mydata, start=list(A=2, B=4, C=1), trace=TRUE)
