How about using mapply, the multivariate version of sapply? Based on your example ... mapply(function(x,y) rpois(x,y), c(1,2),c(0.1,0.8)) HTH Pete -- View this message in context: http://r.789695.n4.nabble.com/sapply-function-and-poisson-distribution-tp4701353p4701358.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
