Create a sequence in R with that alternatively repeats-CodePudding

My homework asks me to create a sequence like this.

(1, 2, 2, 3, 4, 4, 5, 6, 6, . . . , 50, 50)

I'm a newbie to R so would really appreciate your help

CodePudding user response：

You can use rep and alternate the number of repeats. Check ?rep for more information.

rep(1:50, ifelse(seq(1:50) %% 2, 1, 2))

Or, with two reps:

rep(1:50, rep(1:2, 25))
rep(1:50, rep(1:2, length.out = 50))

CodePudding user response：

Short code using integer division:

2:76%/%1.5

This will return a numeric vector.
