There shouldn't be (apart from editing the code), because you really don't 
want something this basic to be unpredictable.

There have been discussions at several times about whether drop=FALSE or 
drop=TRUE should be the default. The decision has always been that 
programmers can cope either way, but that users probably don't expect 
mtx[,1] to be a vector, and that they definitely don't expect mtx[1,1] to be a 
matrix.
