Using seq() and rep() function in R

Question

I need to do the following in R: I have a number (N), for example N <- 7 and I have a length (size), for example size <- 3

And for example if N==7 and size==3, I need to get an output a vector same as:

v <- c(1,1,1,1,1,1,2,2,2,2,2,2,2,3,3,3,3,3,3,3)

you see in v, each number from 1 to size is repeated N times. Is there any way to do this in R without using a for loop?

Answer 1

你可以试试

 rep(seq(size), each=N)
