multivariate simulation
...tivariate distribution. The MASS package allows by mean of "mvrnorm" command to perform a multivariate normal simulation. Is there an equivalent command for an arbitrary multivariate distribution available in the R-language? Thank you in advance.

Re : Information
...istribution function of (X,Y) at each point (xi,yi) and I have not find in R a package that evaluate this function. Is there a such package in R? If no, how can I do to make my simulation succesful? Thank you very much for your assistance.

Re : CDF of a Multivariate Normal
...have to use the values of the cumulative distribution function of a multivariate normal with known mean vector and dispersion matrix. Please, can you tell me if there is a package in R to do that? Thank you very much for your greatly appreciate cooperation.

Calculation of ratio distribution properties
Hi all, Looking to calculate the expected mean and variance of a ratio distribution where the source distributions are gaussian with known parameters and sample values are correlated. I see (from wikipedia: http://en.wikipedia.org/wiki/ Ratio_distribution#Gaussian_ratio_distribution) that this calculation is quite involved, so I'm hoping that someone has already coded a function to

Major update of package actuar
...f ?grouped.data? and ?ogive?. BUG FIX ? An old and nasty out-of-bounds bug could crash R when using the "recursive" method of 'aggregateDist' with a frequency distribution from the (a, b, 1) family. I hope this update will prove useful.
