Hi!

I'm supposed to create a random sample bivariate normal variates of size
equal to 250 with mean vector (-1,1) and cov matrix (1,0.95,0.95,1)

In S language I would write:

> mean<-c(-1,1)
> cov<-c(1,0.95,0.95,1)
> covmat<-matrix(cov,nrow=2,ncol=2)
> mvnorm<-rmvnorm(250,mean,covmat)
... and it should work

I've tried this in R, but it does not recognize "rmvnorm".

(Error: couldn't find function "rmvnorm")

Does anybody knows what function should I use in this case?

My best regards,

Adriane
