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.
