Aggregate points to a fishnet in R (sf)

Показать описание
In this video we create a fishnet grid over a set of points. We then use that grid to aggregate and map our points.

0:48 - making an sf object
2:44 - a first grid
4:40 - making the fishnet
8:55 - aggregating to the fishnet
10:55 - mapping
12:00 - making a function

Great video! I got a question... is it possible to get the % covered by each grid by a set of polygons inside of it with sfdep?

Question: If we want to run this through a Hot Spot Analysis later, how can we maintain the geometry to follow along with your "Hot Spot Analysis in R: GIS Fundamentals" video? Since we turned it to an sf object I am unable to proceed with assigning neighbors and weight. Specifically the mutate() and st_continguity() functions. -Thank You

Thanks a lot for this video! I just wondering how may I export this to a .geojson file for down stream analysis such as Emerging Hot Spot Analysis? Thank you.
