Vectorised over string, width and pad. This is an internal function doing the same thing of str_pad() function in package stringr (except for parameters 'width' and 'length' which must be of length 1), but without depending on package stringi.

str_pad2(string, width, side = c("left", "right", "both"), pad = " ")

Arguments

string

A character vector.

width

Minimum width of padded strings.

side

Side on which padding character is added (left, right or both).

pad

Single padding character (default is a space).

Value

A character vector.

Examples

rbind( str_pad2("hadley", 30, "left"), str_pad2("hadley", 30, "right"), str_pad2("hadley", 30, "both") )
#> hadley #> [1,] " hadley" #> [2,] "hadley " #> [3,] " hadley "
# All arguments are vectorised except side str_pad2(c("a", "abc", "abcdef"), 10)
#> a abc abcdef #> " a" " abc" " abcdef"
# Longer strings are returned unchanged str_pad2("hadley", 3)
#> hadley #> "hadley"
