[R] all combinations of the elements of two vectors

Dear R-help readers, I'm sure this problem has been answered but I can't find the solution. I have two vectors v1 - c(a,b) v2 - c(1,2,3) I want an easy way to produce every possible combination of v1, v2 elements Ie I want to produce c(a1,a2,a3, b1,b2,b3) regards Desmond Desmond Campbell Dept

[R] test for whether dataset comes from a known MVN

Dear all, I have a multivariate dataset containing 100,000 or more points. I want find the p-value for the dataset of points coming from a particular multivariate normal distribution With mean vector u Covariance matrix s2 So H0: points ~ MVN( u, s2) H1: points not ~ MVN( u, s2) How do
