No, it is a package, not a library!
mvtnorm, not splus2R), if I generate 2 bivariate normal samples as follows:
rmvnorm(2,mean=rep(0,2),sigma=diag(2))
[,1] [,2]
[1,] 2.0749459 1.4932752
[2,] -0.9886333 0.3832266

Where is the first sample, it is stored in the first row or the first column?
Does this function store samples row-wise or column-wise?
Hmmm, you could do something to find out which is much faster than
writing this message: Try to generate 3 bivariate samples and look if
you got 3 rows or 3 columns now!
