Hi everybody,
Does anyone have an idea how to count the number of points in each zone A, B and C?
Thanks in advance
Best,
You could create a SAS/Graph gmap representation of the Clark Error Grid, where each area is a gmap polygon (like a 'state' in maps.us), and then use Proc Ginside to see which polygon each x/y point is in.
Thanks a lor for your quick answer. I started from your example "hemoglobin_error_grid" (2nd example). I am not yet very comfortable with the creation of SAS/Graph gmap and the PROC GINSIDE. I will work on it and let you know.
Thanks again!
Best,
Thanks a lot Robert,
The methodology you have described runs perfectly!
Best,
Thanks Rick for the doc!
Best,
See my recent blog article on this topic. Clark Error Grid Graph - Graphically Speakinghttp://blogs.sas.com/content/graphicallyspeaking/
learnt from it .thanks very much.
