In robertschnitman/stringops: String Operations

Concatenate strings together

Description

Concatenate strings together.

Usage

string_concat(a, b, ...)
string_prefix(s, prefix)
string_suffix(s, suffix)
string_flag(s, flag, width, which = c('left', 'right', 'both'))
string_flagv(s, ...)

Arguments

a	A string (character) vector.
b	A string (character) vector.
...	Parameters passed to paste0() or string_flag().
s	A string (character) vector.
collapse	A string by which to separate the elements of a vector.
flag	Character or number to append to a string.
width	Number of characters a string should be.
which	Side to flag a string.

Details

The %&% operator acts similar to BASIC's &, concatenating two elements together. For more general usage, use string_concat(), whose optional inputs get passed to paste0().

string_prefix() and its synonyms prefix a string to a vector, while string_suffix() and its synonyms suffix a string to a vector.

string_flag() is a scalar function that appends a character or number to a string if it does not meet a specified width.

string_flagv() is a vectorized version of string_flag().

The synonym pattern of these functions are s_*() and *() (replace asterisks with prefix, suffix, and flag(v)).

Value

Character vector.
