Thanks. Yes, I wrote rqss, and attempted to follow the structure of
lm, and various analogues,
for example in survival4. My problem seems to be that my lam variable
is not part of
the data frame d, and I don't know how to manipulate the environment
for the formula
so that it is found. T

Great, thanks again, Duncan. And to Peter. I've adopted the enclos =
environment(formula)
solution.

I don't understand the following behavior for a simple S3 class. The
auto-printing at the command line
doesn't behave as I expect. I'm probably missing something, but it might be
a bug.

It may have to do with the results of is.object():
> is.object(1*structure(1,class="testClass"))
[1] FALSE
> is.object(structure(1,class="testClass")*1)
[1] TRUE
> is.object(structure(1,class="testClass"))
[1] TRUE
is.object(x) should be true if x has a class attribute,
but 1*structut
