How do I duplicate values in R?

Question

Assume I have the following vector:

v1 <- c(1, 2, 3, 4, 5)

If I wanted to expand this vector so that there are 50 1 values, 50 2 values, etc., how would I do this? Please let me know if you need any clarification.

Answer 1

Have a look at this:

v1 <- c(1, 2, 3, 4, 5)
rep(v1, 2)
# [1] 1 2 3 4 5 1 2 3 4 5

Or with each (after @Rui's comment):

rep(v1, each = 2)
# [1] 1 1 2 2 3 3 4 4 5 5
