Hi, I have a probably simple problem but I can't solve it alone. I have a list of numbers let's assume it is nb <- c(2,5,3) I want to create a list of concatenated zeros using the first list. The output should be nb_zeros = c(00, 00000, 000) I assume I have to use lapply() et rep() but they do…

Do something like this library(purrr) nb <- c(2,5,3) nb_zeros <- nb %>% map(function(x) rep(0, x)) nb_zeros #> [[1]] #> [1] 0 0 #> #> [[2]] #> [1] 0 0 0 0 0 #> #> [[3]] #> [1] 0 0 0 Created on 2019-01-04 by the reprex package (v0.2.1)
