Hello folks!
I'm trying to create some nice graphs for summary statistics in a
paper. Here is the issue.
I have shapefiles of St Petersburg, Russia, which I can import via
spb <- readShapePoly("/home/sasha/Documents/maps/spb.shp")
I also have data on apartments in the city. For each apartment, I have
the latitude, longitude, and the price.
I would like to plot the price on the map in a "heat" style plot. The
natural way to do this by computing a local average price for a
specified neighborhood around (Lat, Lon) (say, of 0.01 of a degree
across -- I have enough data to make this as fine as I need).
Does anyone have suggestions on the best way to do this?
Thanks!
Aleks
