Please look at ?datasets::randu for David Donoho's translation of RANDU into R. On Mon, Aug 14, 2017 at 12:49 PM, Martin Møller Skarbiniks Pedersen wrote: > Dear all, > > I am trying to learn functions in R and 3D plotting so I decided to try > to plot > the famous bad

[R] Help creating the IBM Randu function

Dear all, I am trying to learn functions in R and 3D plotting so I decided to try to plot the famous bad PRNG Randu from IBM(1). However something is not correct in the function I have created. First I define the function RANDU like this: > RANDU <- function(num) { return
