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.

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

hai, I want to perform a simulation like this：

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. ?
