R from outside program
Hi all,
I'm writing a program in C++ in witch there should be some graphical outputs.
To do so, I would like to use R with the command :
R --no-save < cmdfile.R , where I put the R graphic commands in the
cmdfile.R file.
I call R from my C++ code but as R seems to run in batch mode, there are no
graphical outputs!
How can I do to get the graphics outputs ?

autocorrelation test
Hi all,
I would like to test the relevance of a vector field (i.e. if the
vectors are organized or not).
To do so, I would like to use an autocorrelation test, so that I have
two questions:
- is the Watson test applicable to that perpuse ?
- is the kuiper test applicable to that purpuse ?
Regards

Problem to interpret wilcox.test
I've got two set of data :
22.45 21.56 20.48 19.59 21.52 = A
and
22.15 21.98 20.42 20.58 19.61 = B
I perform a wilcox.test on this two set
wilcox.test(A, B) and I'd this answer:
Wilcoxon rank sum test
data: A and B
W = 12, p-value = 1
alternative hypothesis: true mu is not equal to 0
Should I interpret that there is no difference between the two sets ?

Linux configuration (Ubuntu)
Hello all,
I have been a R user for about a year now, running on a MS Windows machine.
I am in the process of making a complete switch to open-source. Linux is a
new world to me. Ubuntu was my selection of the various distributions.
Please pardon this very basic question (I was unable to locate an answer on
R or Ubuntu). I used Synaptic to download the necessary files to run.

Hi,
I would like to eliminate the trend of a set localised (with x an y) data.
I try to fit a linear model to the data:

I've got so a model. My question is how can I do to subtract the model from
the initial f data ?
