Hi Dimitris,
Thanks for your reply. But this is not exactly what i am after. I want to
find the probes that falls into certain regions. In your solution it will
ignore the second probe if it falls into the same region as the first one.
Is there any vector trickb uilt in R to find whether probes fall into
certain regions?
best,
salih
