Question about checkTmvArgs function in rtmvnorm (package tmvtnorm)
Hello!
I was wondering if it's possible to see the actual code of
checkTmvArgs function that is part of the code for rtmvnorm (which is
below - I just typed "rtmvnorm" on the prompt). I get an error:
Error in checkTmvArgs(mean, sigma, lower, upper) :
sigma must be a symmetric matrix
At the same time I am pretty sure that the matrix I am passing as
sigma is a var-covar matrix

how to get samples from rtmvnorm with large dimensions
Hi, dear all,
I wish to get one sample (2500-d vector) from the truncated multivariate
normal distribution, so I choose use the R function rtmvnorm() to do this.
But the error information shows that for this function, the dimension should
be lower than 1000,
So could you help me to find out if there's any solution could do such
sampling from a truncated multivariate normal distribution

under what conditions would rtmvnorm (from package tmvtnorm) produce all NaNs
Hello!
I am trying to generate a sample from a truncated multivariate normal
distribution using rtmvnorm.
I am using Gibbs because my alpha (line below) is teeny-tiny ( 4.083475e-64 )
alpha = pmvnorm(lower=lower, upper=upper, mean=btilde, sigma=MyVarCovar).
When I try my Gibbs run, it takes quite a long time (with 10,000
iterations and 5,000 iterations burn-in) ~ 22 sec. And then what I get

mtrr error
I need your help and DEL's tech support doesn't provide any help on this
one.
We have a lot of different type of DELL desktops from old-type
hyper-thread cpu, to dual-core and quad-core cpus (most are Xeons). We
run all versions of CentOS, but most are latest 5.5 (also up-to-date)
and are very happy about that. The primary software on those Linux
systems is IDL, which uses OpenGL

rtmvt
I want to use the rtmvt from the {tmvtnorm} package using the "gibbs"
algorithm but how to i specify the nested function rtmvnorm to use gibbs as
well?
Right now I am using the code:
for (i in 1:g){
for (j in 1:n){
sgamma[,,i,j] = rtmvt(n=50, mean=mu[i,j], sigma[i,j],
df=nu[i], lower=rep(0,2),algorithm="gibbs")
}
}
heres an example of one iteration:

Games performance with wine
I've been using Linux Ubuntu for a few days, but I already love it :) However, when I'm running windows games under wine, I get less than 10fps, while under windows they work really fast. I have installed latest Nvidia drivers from ubuntu repositories and Direct X 9c under wine (yes, dxdiag works, and it passes all the tests). I have also seen on youtube, that many people don't have

Isolinux freezes loading configuration file.
Hi All,
I've got a simple isolinux cd loading a floppy image via memdisk, that
boots reliably on 14 of 15 platforms, but intermittently hangs on one
and, unfortunately, I can't substitute the platform. The behavior is
weird. If I cold boot the system with the CD already in the drive, it
*usually* boots to completion. Warm boots are hit-or-miss. If there's

tmvtnorm: version 1.0-2
Dear R users,
the tmvtnorm package, the package for the truncated multivariate normal and Student-t distribution, has been updated on CRAN.
The major changes in version 1.0-2 (2010-03-04) are:
* The package now provides methods for the truncated multivariate Student-t distribution, i.e. random number generation, density function, distribution functions like rtmvt(), dtmvt() und ptmvt() and

I plugged in the card, and introduced the loopback plug. I cleared the

truncated distributions
I am sampling from the truncated multivariate student t distribution "rtmvt"
in the package {tmvtnorm}. My question is about the mean vector. Is it
possible to define a mean vector outside of the truncated region? Thank you
in advance for any help.
