The columns represent multinomial cell numbers, and within a row the columns are all samples from the same multinomial distribution. The code is a modification of that in the \code{impute.polyreg} function in the \code{MICE} package. } \usage{ rMultinom(probs, m) } \arguments{ \item{probs}{matrix of probabilities} \item{m}{number of samples for each row of \code{probs}} } \value{ an integer matrix having \code{m} columns } \seealso{\code{\link{rbinom}}} \examples{ set.seed(1) w <- rMultinom(rbind(c(.1,.2,.3,.4),c(.4,.3,.2,.1)),200) t(apply(w, 1, table)/200) } \keyword{distribution}
