[R] Add values of rlm coefficients to xyplot

[PtitBleu]

Thank you very much David for the advice !
I haven't checked the plyr and data.table packages but here is the script to
replace the for loop ::

dfrlm1<-as.data.frame(do.call("rbind", lapply(split(df1, df1$Name),
function(X){coef(rlm(col2 ~ col3, data=X))})))
names(dfrlm1)<-c("Intercept", "Slope")

Have a nice end of day,
Ptit Bleu.
