ave2 <- function (x, ..., FUN = mean)
{
if(missing(...))
x[] <- FUN(x)
else {
#g <- interaction(...)
You're right. But I guess my confusion is proof that it can be
confusing.

1) I think a good amount of the popularity of base::reshape alternative is due
to the complexity of reshape documentation. It is quite hard (at least it is
for me) to figure out what argument is needed for respectively "long to wide"
I suspect this is as meant, but it is "multiply", the adverb, not the verb. So
it might be worth rephrasing, but "multiple" would be wrong (it is about cases
where you at one position have several partial matches, not several positions
where you have a partial match). "Non-uniquely partially mat
