Of course. Did you not see my comment about 'to protect code against
redefining functions'?

Pijus,
My 2 cents, which might be post-hoc rationalization.
If your class 'is' a list, with additional information, then
setClass("Test", contains="list")
and you're ready to go.
On the other hand, if your class 'has' a list, along with other
information, create an accessor
setGeneric("test",
Thank you.
When I tried to set as.list() in baseenv(), I learned that its bindings
are locked. Does this mean that the thing to do is just to write my own
"lapply", which does the coercion using my "private" as.list(), and then
invokes the base lapply()?

What you have not said is that this is an S4 class.

Hi,
I would like to get lapply() to work in the natural way on a class I've
defined. As far as I can tell, lapply() needs the class to be coercible
to a list. Even after I define as.list() and as.vector(x, mode="list")
methods, though, I still get an "Error in as.vector(x, "list") : cannot
coerce
