Let me ask a little more about the DUP argument.
In the manual, I can see that only reference copy happens when passing an

if DUP=FALSE. Then, what happens when returning it in a list, if DUP=FALSE?

My current approach for model summaries is to use the xtable package and
write things as HTML tables.
It was an HTML approach that Gabor suggested,using R2HTML, and that worked
well, but I will try xtable as well.
As always with R, there is a solution if you know where to look.

That's the advantage of having an R interface to RF: you can do such
automation rather easily. E.g.,
twoStageRF - function(x, y, nVar=round(0.1*ncol(x)), ...) {
imp - randomForest(x, y, importance=TRUE, ...)$importance[,3]
cutoff - sort(imp, decreasing=TRUE)[nVar]

Hello,
Is there a way to get complex sample variances in the survey package on summary
statistics other than means? If not, can they be added to a future version? It would
be be great to have them on totals, quantiles, ratios, and tables (eg row percent,
columns percent, etc).
Thanks.
