How to assign more than one value for "each" argument in "rep" function in R? A trivial example, where each value in a vector is 3-times repeated in a row:
a <- seq(2,6,2)
rep (a,each = 3)
However, if I add more than one value in "each" argument in order to change the number of repetition of each value, it doesn't work properly:
rep (a, each = c(2,4,7))
How to solve it? Thank you in advance.
回答1:
well, depending on what you think the output should be, I'm guessing you want the times= parameter
rep (a, times=c(2,4,7))
# [1] 2 2 4 4 4 4 6 6 6 6 6 6 6
See ?rep for the difference
