Does R have a function like the S(plus) function, lmsreg, Least Median of Squares Regression? I am using R-0.61.

Hello, My name is edwin, I come from Indonesia, Can you help me, I want package which is contain lqs and lmsreg. I need fast... Can you help me to create bootstrap regression ?? Thx Edwin [[alternative HTML version deleted]]

...nto sqrt() didn't think it would be negative. So this suggests a problem in the lqs_fitlots function call, but I haven't looked at that. I understand that the problem may be that bootstrapping such a small data set is insane, but I'm just copying Efron and Tibshirani (who do this with lmsreg). So the problem may be only that more informative error messages are needed (or failure codes, although failure codes are somewhat antithetical to the S/R spirit). Anyway, just stuffing negative numbers into sqrt() doesn't look good. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-....

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
