[R] how to get this kind of binomial distribution simulation number?

[Huntsinger, Reid]

rmultinom(n=1,size=500,prob=c(0.3,0.5,0.2))

to get n samples each of size 500 just use the "n=" argument.

hai, I want to perform a simulation like this£º

Suppose that I have one population  ,it's size is 500, is composed of x,y
and z.  The probability of x, y and z is respectively is 0.3, 0.5, 0.2. I
wan to simulate a new same size population based ratio of x, y and z, how
can I get and assess  the number of x, y and z. ?
