lm's "predict" function offers an "interval" parameter to choose between
'confidence' and 'prediction' bands. In the package "robust" and for "lmRob",
there is also a "predict" but it lacks such a parameter, and the documented
"type" parameter has only "response" offerred. Is there some way of
"robust" does not adopt a normal model for the y variable, what's the
proper interpretation of the standard errors for slope and intercept it yields?
A reference?

Joyful.
I'm adapting a FORTRAN 77 package for use with R. Pretty
straightforward.
Except for a glitch it took me some time to figure out. This existing
package has subroutines which have parameters called "NA". So, I called
subroutines like

Like many software assemblies, R is updated frequently. Also, it
creates its own release-numbered directory when it is installed.
Packages get dumped into the subdirectory "library". I have a personal

packages for convex optimization along these lines for R.
TIA.
