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