Re: [R] Brillouin index

It's a pretty simple formula, according to the sources I found. Here's a function that looks right to me, but I have no independent calculation with which to check it. (no guarantees!) Hb <- function(ns) { N <- sum(ns) (lfactorial(N) - sum(lfactorial(ns)))/N } > ns <- c(3,5,2,8) > Hb(ns) [1]
