operator_add: Concatenate Two Character Vectors

In stringi: Fast and Portable Character String Processing Facilities

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.
