Just a suggestion: package mvtnorm Berend -- View this message in context: http://r.789695.n4.nabble.com/Multivariate-normal-density-in-C-for-R-tp3624602p3625954.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
