There was recently a discussion here on how to tell if a number was integral. Did that prod someone into change as.hexmode in R-3.1.2 so that it aborts if given a number to big to fit into a 32-bit integer? It returned NA, with two warnings in R-3.1.1. % R-3.1.2 --quiet --vanilla
as.hexmode(c(10^c(0,9,18)))
Error in if (is.double(x) && all(is.na(x) | x == as.integer(x))) x <- as.integer(x) : missing value where TRUE/FALSE needed In addition: Warning message: In as.hexmode(c(10^c(0, 9, 18))) : NAs introduced by coercion
