R code for selecting places spatially and by time
Hi all
The code of trying to write relates to selecting properties (given by x
and y co-ordinates) spatially (distance "X" from "infected" properties
identified by date) over a certain time period.
i.e. what properties are within 3 km from properties infected on
"2008-01-01" over the last 14 days.
Is any one able to give me some clues on how to write code to solve
