following order: regex
, fixed
and
class
. Thus, if you specify regex
and
class
, only the first one will be used.
Returns a list of integer matrices. The first column gives
the start positions of the matches, and the second one
gives the end position. Double NA
s iff not found or
NA
argument is given.
