%s<% {stringi}R Documentation

Compare Strings with or without Collation

Description

Relational operators for comparing corresponding strings in two character vectors, with a typical R look-and-feel.

Usage

e1 %s<% e2

e1 %s<=% e2

e1 %s>% e2

e1 %s>=% e2

e1 %s==% e2

e1 %s!=% e2

e1 %s===% e2

e1 %s!==% e2

e1 %stri<% e2

e1 %stri<=% e2

e1 %stri>% e2

e1 %stri>=% e2

e1 %stri==% e2

e1 %stri!=% e2

e1 %stri===% e2

e1 %stri!==% e2

Arguments

e1,e2

character vectors or objects coercible to character vectors

Details

These functions call stri_cmp_le or its friends, using default collator options. Thus, they are vectorized over e1 and e2.

%stri==% tests for canonical equivalence of strings (see stri_cmp_equiv) and is a locale-dependent operation. On the other hand, %stri===% performs a locale-independent, code point-based comparison.

Value

All the functions return a logical vector indicating the result of a pairwise comparison. As usual, the elements of shorter vectors are recycled if necessary.
