Hi
If I get a p-value less than 0.05 does that mean there is a
significant relation between the 2 ranked lists? Sometimes I get a low
correlation such as 0.3 or even 0.2 and the p-value is so low , such
as 0.01 , does that mean it is significant also? and would that be
interpreted as

I have a dist object containing 1 row that is only NA (not very intelligent

Many thanks.
Is there a way to give me the number of the row, if I have the row name?
B.
a= object
'w' = name
match('w', names(a))
# or
which(names(a)=='w')
# or
but deletion should work with the number and/or with the name.
Hello,
Function dir() is very useful for finding files.
However, is there a analog function for finding directories
based eg on a pattern ?
Apologies if I've missed something obvious.
Thanks

access networked PCs directories/files with R ?
Dear group,
I would like to know if there is an easy way to access several
networked PCs directories/files from one PC with R ?
Concerned OS is windows.
I can for instance use dir() on my current PC.
Is there a way to do dir() on a connected PC ?

I have a data frame and would like to convert it into a matrix, how do I do
that?
either use the df for the initialisation values
mat = matrix(df, ...)
or
as.matrix() could do the trick.

No hit key solution sorry, but may help :

My R script needs to pause or wait for a key or mouse on each graph. I used

Dear list,
My R program has to deal with a 3rd party java program.
I would like to know, automatically, which version
of java is used when both programs are speaking together.
Does anybody have an idea how to obtain such info from R ?
Thanks

If you use the java version fom the classpath you can type inside R:
system(java -version)
or type java -version in the shell or console.
This works for my config : R.2.5.1. under windowsXP.
(apologies for forgetting precising it).
Many thanks for your answer.
