Heinrich,
You could create your own function mywithin()
by inserting a couple of rev()'s in within.data.frame().
In within.data.frame(), replace the two commented lines
with those immediately following:
mywithin <-

I am using function 'within' in R.2.9.1 to add variables to an existing

are added to the data in reverse order.
For example:
x <- data.frame(a = 1:3, b
Try this:
transform(transform(x, c = a ^ 2, d = b ^2), e = c + d)

Dear R community,
I am using function 'within' in R.2.9.1 to add variables to an existing
data.frame. This works wonderful, except for one minor point: The new variables
are added to the data in reverse order.
For example:
x <- data.frame(a = 1:3, b = 4:6)
y <- within(x, {
c = a^2
d =
