Dear Happy R-users & experts, I am in need of advice, While working with spatial data (x & y coordinates of seed locations) I have come accross the problem that I need to convert my point data into a matrix or grid system. I then need to count how often a point falls into a certain position in the matrix or grid. I have searched all day online, asked collegeas but nothing works.
Sadly my R "box of tricks" has run out. My (point) data looks like this; x y 2.3 4.5 3.4 0.2 and continues for another million records. Now my question; is there any function that is able to "count" how often a point falls into a grid based on the x and y location? So I need to discretize the spatial locations to a regular grid and then counting how often a point occurs. Many thanks for your thoughts on this problem.
