Dear S-Plus users:

Has anyone written a (S-)function computing the distribution function of
the Euclidean norm of a (centered) multivariate Gaussian random variable G:

P( ||G|| <= x ) = ?

Or, more generally, does anyone know of a paper describing how to compute
this probability efficiently?

Many thanks for any answer!
