%s<% | R Documentation |
Relational operators for comparing corresponding strings in two character vectors, with a typical R look-and-feel.
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
e1 , e2 |
character vectors or objects coercible to character vectors |
These functions call stri_cmp_le
or its
friends, using the default collator options.
As a consequence, they are vectorized over e1
and e2
.
%stri==%
tests for canonical equivalence of strings
(see stri_cmp_equiv
) and is a locale-dependent operation.
%stri===%
performs a locale-independent,
code point-based comparison.
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.
