The replacement can contain
$i, which substitutes for the ith set of parentheses in the match string. E.g.,regexprep("Bill Dunn",'(\w+) (\w+)','$2, $1')returns "Dunn, Bill"
options may be zero or more of
- ‘once’
- Replace only the first occurrence of pat in the result.
- ‘warnings’

regexpi). Alternatively, use (?i) or (?-i) in the pattern.- ‘lineanchors and stringanchors’
- Whether characters ^ and $ match the beginning and ending of lines. Alternatively, use (?m) or (?-m) in the pattern.
- ‘dotexceptnewline and dotall’
- Whether . matches newlines in the string. Alternatively, use (?s) or (?-s) in the pattern.
- ‘freespacing or literalspacing’
- Whether whitespace and # comments can be used to make the regular expression more readable. Alternatively, use (?x) or (?-x) in the pattern.
