8 CloudStat: Repeat Function, rep() (R Language Tutorial)

This tutorial is about repeat function, rep().
To output 100 "1"s, instead of typing 1 for hundrend times, we should use repeat function, rep(1, each=100) or simplify as rep(1,100)

Here are some more examples:
rep(c(1,2,3,4),10)
rep(1:5,10)
rep(seq(1,50,5),10)
rep(c("NOR","IND","ARM","RUS","AZE"),8)
