comment Create Zonal Grid in R
Thanks for your answer @yellowcap. I am wondering if there is anyway to get rid of the double for loop. It could be very slow for a large matrix.

I think it makes sense, my concern is how to perform spatial query in R.

I will consider it as an extent. So do you have some suggestions on methods?

I think clipping can do this, but if I have a lot of zones to process?

is there anyway just perform spatial query rather than cropping the image? Cropping might be very slow for processing.
