We did think about this a lot, and decided it was better to have
something like rowQ, which really returns requested order statistics,
letting the user manipulate them on the return for their own version of
median, or other quantiles, was a better approach. I would be happy to
have this in R it

Hi,
I've got a version of rowMedians(x, na.rm=FALSE) for matrices that
handles missing values implemented in C. It has been optimized for
memory and speed. To avoid coercing integers to doubles, and hence
allocate an additional 200% memory, there is one C function for
integers and one for double
