Hi
Indeed the help page says ...
"the indices of the identified points, in the order they were identified"
... and that is a complete lie.
Sorry about that :(
The simplest thing would be to correct the help page.
It would be possible to have identify() return the order, though for
backward compatibility that should not be the default, so would require
another argument to identify().

Hi,
Using identify function, I think I should get the index of the selected
points in the order I clicked them. This is what I read in the help. But
I feel they are ordered. Please let me know what I missed.
In the following example, I clicked on the points labelled 7, 5 and 1,
but I get 1, 5, 7 as output.
set.seed(0); x = rnorm(10); y = rnorm(10); plot(x,y); text(x, y,
seq(x)); sel = identify(x,y); sel
[1] 1 5 7
Any help appreciated,
Samuel
