No equivalent in base R, but you could always use ?apply:

apply(x, 1, median)

assuming "x" is an array or is coercible to a array.

I have a C-function that does this as part of my personal R package (not available from CRAN). It has the same time savings as "rowMeans" has over apply(x, 1, mean). Contact me offline if you would like a copy.
