Dear all, Using rmultinom() in a stochastic model, I found this function returns an error message 'NA in probability' for an infinite probability.
Maybe, a more precise message will be helpful when debugging. > rmultinom(1, 3:5, c(1/2, 1/3, Inf)) Error in rmultinom(1, 3:5, c(1/2, 1/3, Inf)) : NA in probability vector > rmultinom(1, 3:5, c(1/2, 1/3, NA)) Error in rmultinom(1, 3:5, c(1/2, 1/3, NA)) : NA in probability vector For rgeom() or rbinom(), we got a warning for infinite probability : > rbinom(1, 3, Inf) [1] NA Warning message: In rbinom(1, 3, Inf) : NAs produced > rbinom(1, 3, NA) [1] NA Warning message: In rbinom(1, 3, NA) : NAs produced > rgeom(1, Inf) [1] NA Warning message: In rgeom(1, Inf) : NAs produced > rgeom(1, NA) [1] NA Warning message: In rgeom(1, NA) : NAs produced Maybe, it could be better to harmonize the behavior for infinite probability.
