[R] Packages in R for least median squares regression and computing outliers (thompson tau technique etc.)

[lalitha viswanath]

Hi
I am looking for suitable packages in R that do
regression analyses using least median squares method
(or better). Additionally, I am also looking for
packages that implement algorithms/methods for
detecting outliers that can be discarded before doing
the regression analyses.

Although some websites refer to "lms" method under
package "lps" in R, I am unable to find such a package
on CRAN.

I would greatly appreciate any pointers to suitable
functions/packages for doing the above analyses.

Thanks
Lalitha
