I expect you could do something like
let(MyO, ThisProperty = ThisValue)
with a declaration for the function like this:
let <- function(obj, ...)
{
properties <- list(...)
assign( something, envir = something)
}
and playing around with the sys.frame function, substitute, etc., to
fill in the gaps. I think the details are in the R extensions manual.
Look at
get("mode<-")
for an example of a function call constructed from the arguments, and
an assignment made in a parent frame.
