[R] random generation of a factor

[Christian Bieli]

Dear Dave and Roland

Thanks for your answers! I think sample() does the job I'm looking for.
I also came up with rmultinom(), but could not make it working, because 
I don't want several multinomial distributed vectors, but one vector 
with K levels of predefined proportions. Propably there is a way to do 
that with rmultinom() - Dave, could you make up a short example?

Best wishes
Christian
