Select random element in a list of R?

Question

a<-c(1,2,0,7,5)

Some languages have a picker -function -- choose one random number from a -- how in R?

Answer 1

the above answers are technically correct:

sample(a,1)

however, if you would like to repeat this process many times, let's say you would like to imitate throwing a dice, then you need to add:

a<-c(1,2,3,4,5,6)
sample(a, 12, replace=TRUE)

Hope it helps.
