PL/R etc.

I don't know whether anybody active on the list has R (and in particular
PL/R) experience, but just in case... :-)

i)   Something like APL can operate on an array with minimal regard for
index order, i.e. operations across the array are as easily-expressed
and as efficient as operations down the array. Does this apply to PL/R?

ii)  Things like OpenOffice can be very inefficient if operating over a
table comprising a non-trivial number of rows. Does PL/R offer a
significant improvement, e.g. by using a cursor rather than trying to
read an entire resultset into memory?
