latlon.colnames.check: obsolete - see latlon_is.valid()

In ejanalysis/proxistat: Create a Proximity Score in Each Census Unit, Based on Distances to Specified Points (as in EPA's EJScreen tool, for example)

obsolete - see latlon_is.valid()

Description

Used by functions like get.distances to check input parameters frompoints and topoints

Usage

latlon.colnames.check(mypoints)

Arguments

mypoints

A matrix or data.frame

Value

Returns a vector of colnames such as c('lat', 'lon') or stops if problem found

get.distances.all which allows you to get distances between all points, get.distances.prepaired for finding distances when data are already formatted as pairs of points, get.nearest which finds the distance to the single nearest point within a specified search radius instead of all topoints, and proxistat which calculates a proximity score for each spatial unit based on distances to nearby points.

get.distances which allows you to specify a search radius and get distances only within that radius which can be faster, get.distances.prepaired for finding distances when data are already formatted as pairs of points, get.nearest which finds the distance to the single nearest point within a specified search radius instead of all topoints, and proxistat which calculates a proximity score for each spatial unit
