Re: [R] Identify does sort the locations
Hi Samuel GRANJEAUD,
Isn't this loop more simple to retain the click-order:
result = numeric(n)
for (i in 1:n) {
id = identify(x, y, n=1)
result[i] = id
}
Hope this helps,
Best regards,

Re: [R] Identify does sort the locations
Thanks Paul. I have started using locator(). I also found the gatepoints package that sounds interestering. https://CRAN.R-project.org/package=gatepoints Happy R, Samuel On 15-02-2018 21:50, Paul Murrell wrote: Hi Sorry, I think this has always been the behaviour (and the documentation has always been wrong).

Re: [R] Identify does sort the locations
Hi Paul, Thanks for your answer. I am wondering if in the previous versions, let's say 2.1x, the data were in the selection order... Let me know if there a R fonction taht I can code. Do you think I should use locator function and match points on my own?

Re: [R] Identify does sort the locations
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().
