[R] Tukey's biweight

I want to estimate the center of a distribution with lots of outliers in one
tail, and thought I would use a function such as S-plus's location.m() with
psi.fun=bisquare (as per MASS 3 p. 131). However, R seems not have such a
function, so my questions are:
1) Is there an R equivalent to location.m()?
2) Would huber() give me results that are similar (i.e., close enough)?

Thanks.

If at first you don't succeed, you must be a programmer.
