You could do something like
?mq <- function(a) {
? ? force(a)
? ? list(getA = function()a,
? ? ? ? ?setA = function(newA) a <<- newA,
? ? ? ? ?fun = function(x)x^a
? ? )
?}
to make it clear that you expect people to look at or change
fun's 'a'.
Once you start doing a lot of that though you may as well go the whole OO hog and use the proto or R.oo packages... Barry
