...tivar combination has little effect the variability may be large, while if it has a dramatic effect (kills everything!), there may be no variability to speak of. John Maindonald.

I'm running Windows NT4. Rcmd does not seen to read the command line. Rterm and other things work well. For example "Rcmd check --help" fails with the command interpreter trying to find a program or file called "check."

Hello everyone. If I do f <- function(n){max(rnorm(n))} plot(sapply(rep(5000,4000),f)) #[this takes my PC about 30 seconds] then I get something quite unexpected: gaps in the distribution. For me, the most noticable one is at about 3.6. Do others get this? Is it an optical illusion? It can't be right, can it? Or maybe I just don't understand the good ol' Gaussian very

Dear R-people Does someone have a routine to ngenerate inverse-gaussian random numbers. I am thinking of something similar to rinvgauss, pinvgauss etc. in S-plus. best regards Helgi -- Helgi Tomasson FAX: 354-552-6806 University of Iceland PHONE:354-525-4571 Faculty of Economics and Business Administration

Hi folks: Is there a lookup function that returns the variate given the cumulative probability for an object returned by the density(...) function? > mydata _ as.vector(mymatrix) > mydata.density _ density(mydata) > mydata.p80 _ lookup(mydata.density, p=0.8) # is there any function to accomplish this task? Thanks. Rajiv. -------- Rajiv Prasad, Postdoctoral Research Associate,

Dear People, Consider the following fragment of R code choose <- function(n,r) { if( is.integer(n) && is.integer(r) && n > 0 && r >= 0 ) { .C("choose",as.double(n),as.double(r),comb = double(1))$comb } else stop("n must be a positive integer and r a non-negative integer.") } This is a practice function (n choose r), which I
