mvtnorm package
Dear all,
I would like to ask information about the package mvtnorm in R.
It is very useful for me the "qmvnorm" comand, but I see that it can
compute only quantile for equicoordinate. Is it possible to have a
curve (or a set of values) if we don't want equicoordinates?
Thank you
Best regards
Antonio.

help with multivariate analysis
dear R users,
I need some help for multivariate analysis.
I have 2 anaesthetic treatment groups (20 patients/group) where I
register heart frequency and pressure for 60 min (repeated measures
every 5 minutes). I would like to perform a test to check if treatments
are different in controlling freq and pressures during the anaesthesia,
but i would like to have also an overall measure and not

I/O size distribution?
Hello
I have read that under Solaris one can use DTrace to get I/O request
size distribution on a global scale (also on a per process/pid basis).
See for example
http://prefetch.net/articles/observeiodtk.html
Can anyone?recommend?an alternative to get similar information under
CentOS? I looked into dtrace for linux but it seems still work in
progress, even putting aside CDDL issues ...

Hello anyone,
I'm trying to install R on Mandriva 2006 distribution via rpm file with the

Rpart - user defined split functions
Dear all,
I'm writing my own method to be used in Rpart by defining the list of
functions named init, split and eval. I'm following the example given in the
file 'tests/usersplits.R' in the sources.
By now I'm able to define the split function (and it works correctly in the
tree construction) while I have some problems with the init and the eval
function.

cross-validation in rpart
Dear R users,
I know cross-validation does not work in rpart with user defined split
functions. As Terry Therneau suggested, one can use the xpred.rpart function
and then summarize the matrix of the predicted values into a single
"goodness" value.
I need only a confirmation: set for example xval=10, if I correctly
understood a single column of the matrix obatined by xpred.rpart gives

I recently moved to an AD environment. I'm still keeping a samba servers

rpart - the xval argument in rpart.control and in xpred.rpart
Dear R users,
I'm working with the rpart package and want to evaluate the performance of
user defined split functions.
I have some problems in understanding the meaning of the xval argument in
the two functions rpart.control and xpred.rpart. In the former it is defined
as the number of cross-validations while in the latter it is defined as the
number of cross-validation groups. If I am
