str_multi_match

strMultiMatch

regular expression: if it has bracketed sections, these
submatches are returned

pattern

is the string to match against. This vector should be the same
length as the pattern vector, or the patern vector should be length one.

text

logical whether to drop rows with no matches

dropEmpty

are additional parameters passed to regexec and regmatches. I
haven't tried this: it may need two separate variables containing lists of
params, since this will send everything to both functions.

Be careful: this may throw funny results for exotic regex, but
 so far, it seems okay. it also drops the first result which always seems to
 be a duplicate or whole-string match

This is a set of simple utilities for various data
manipulation and testing tasks.  The goal is to use core R tools well,
without bringing in many dependencies. Main areas of interest are
semi-automated data frame manipulation, such as converting factors in
multiple binary indicator columns. There are testing functions which
provide 'testthat' expectations to permute arguments to function
calls. There are functions and data to test extreme numbers, dates,
and bad input of various kinds which should allow testing failure and
corner cases, which can be used for fuzzing your functions. The test
suite has many examples of usage.
