The mean of the distribution may be a d-dimensional vector. The covariance matrix should be given as a d x d non-negative definite matrix if supplied with the parameter `cov`

. It can also be given, if cov is missing, by a vector `sd`

for the marginal standard deviations and a scalar `rho`

implying a constant correlation between all the marginals. If the covariance structure of the marginals is supplied in this way, `sd`

should be a d-dimensional vector,
and `rho`

should be scalar. The dimension `d`

may be inferred from other arguments.
The code of this function is a mere wrapper for the function with the same name from the library `mvtnorm`

. It was written to provide compatibility with S-Plus, hence the long list of parameters
