[R] Defining vectors with per-determined correlations

I need to define three vectors x, y, z (each of length 100) such that the pair-wise correlations of the vectors have per-defined values r1 and r2. More specifically I need to define x, y, and z so that:
corr(x,y) = r1
corr(y,z) = r2
Is there any easy way to accomplish this with R?
