Format number as fixed width, with leading zeros [duplicate]

by

There are several solutions to this.

One of them is to use sprintf. This uses C style formatting codes embedded in a character string to indicate the format of any other arguments passed to it. For example, the formatting code %3d means format a number as integer of width 3:

a <- seq(1,101,25)
sprintf("name_%03d", a)
[1] "name_001" "name_026" "name_051" "name_076" "name_101"

Another is formatC and paste:

paste("name", formatC(a, width=3, flag="0"), sep="_")
[1] "name_001" "name_026" "name_051" "name_076" "name_101"
