DiagnoseFailure
R Documentation
Visualize points that could not be mapped using RapidPolygonLookup()
Description
This functions plots the points that could not be mapped using RapidPolygonLookup()
The points are overlayed on the polygons to contextualize their
geographical location and understand the reason behind their exclusion.
Usage
DiagnoseFailure(XY.polys, poly.list = NULL)
Arguments
XY.polys
output from function RapidPolygonLookup()
poly.list
polygon list with 3 or 4 elements: data, polys, poly.centers, and possibly ranges. Needs to be supplied if RapidPolygonLookup() was run with keep.data= FALSE
