operator_add: Concatenate Two Character Vectors#

Description#

Binary operators for joining (concatenating) two character vectors, with a typical R look-and-feel.

Usage#

e1 %s+% e2

e1 %stri+% e2

Arguments#

e1

a character vector or an object coercible to a character vector

e2

a character vector or an object coercible to a character vector

Details#

Vectorized over e1 and e2.

These operators act like a call to stri_join(e1, e2, sep=''). However, note that joining 3 vectors, e.g., e1 %s+% e2 %s+% e3 is slower than stri_join(e1, e2, e3, sep=''), because it creates a new (temporary) result vector each time the operator is applied.

Value#

Returns a character vector.

Other join: stri_dup(), stri_flatten(), stri_join_list(), stri_join()

Examples#

c('abc', '123', 'xy') %s+% letters[1:6]
## [1] "abca" "123b" "xyc"  "abcd" "123e" "xyf"
'ID_' %s+% 1:5
## [1] "ID_1" "ID_2" "ID_3" "ID_4" "ID_5"
