Hi: Try (install package sos first if necessary):
library(sos) findFn('M-estimator') This produced 34 hits on my machine (not quite as productive as Petr's search :), but it identifies a few packages that contain functions for robust estimation. It's also a good way to get familiar with a very useful search mechanism to find R functions in the maze of available packages. Typing RSiteSearch('M-estimator') at the R prompt is another way to search within R.
