Duplicate and concatenate strings within a character vector

Dependency-free drop-in alternative for stringr::str_pad().

Usage

str_pad(
  string,
  width,
  side = c("left", "right", "both"),
  pad = " ",
  use_width = TRUE
)

Adapted from the stringr package.

string: Input vector. Either a character vector, or something coercible to one.
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).
use_width: If FALSE, use the length of the string instead of the width; see str_width()/str_length() for the difference.

A character vector.
