[R] sort a list?

[rkevinburton at charter.net]

I am trying to sort a list and the data is obiously not in the right format. I am trying:

x <- list()
x[["A"]] <- 1
x[["B"]] <- 2

order(x)

But am getting:

Error in order(x) : unimplemented type 'list' in 'orderVector1'

How should I change the list so that it can be sorted? What kinds of objects (classes of objects) can be sorted?

Thank you.
