When you say probability, do you actually mean the density function? http://en.wikipedia.org/wiki/Probability_density_function The probability that a random point belongs to a region is the integral of the density function over that region. If the region is a single point, then this integral is zero. Functions related to a multivariate normal distribution may be computed using package http://cran.at.r-project.org/web/packages/mvtnorm/index.html Petr Savicky. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
