RFC: adding an 'exact' argument to [[
Hi again, Robert has committed the proposed patch to R-devel. So [[ now has an 'exact' argument and the behavior is as described: Seth Falcon <sfalcon at fhcrc.org> writes:
1. [[ gains an 'exact' argument with default value NA
2. Behavior of 'exact' argument:
exact=NA
partial matching is performed as usual, however, a warning
will be issued when a partial match occurs. This is the
default.
exact=TRUE
no partial matching is performed.
exact=FALSE
partial matching is allowed and no warning issued if it
occurs.
