[R] generate fourth vector based on known correlations

I am trying to generate a fourth vector,z, given three known and fixed vectors, x1,x2,x3with corresponding known and fixed correlations with themeselves and with z. That is, all correlations are known and prespecified. How can I do this? Thank you, ben
