Dear Matias

When I run the following code I get 2 warnings:
lmrob.S(): refinements did not converge (to tol=1e-07) in 200 iterations 

library(robustbase)
test <- data.frame(lconc=c(3.081910,3.165475,2.501436,3.650658,
                           3.044522,3.660994),
                   dist=c(100,180,280,30,220,6))

res <- lmrob(lconc~dist, dat=test)

res$converged gives TRUE as the IRWLS iterations after the lmrob.S() have converged.

It would be nice to have also the convergence status of lmrob.S() in the result object of lmrob().

Kind regards

René

P.S.
