splitNearDist: Fast Near Distance for Spatial* objects.

In jacpete/jpfxns: JP Functions

Description

splitNearDist splits Spatial* objects from the (sp) package using seqSPDF, and runs rgeos::gDistance() on the lists to obtain the nearest distance or nearest distance matrix. Behaves like NEAR in ArcGIS.

Usage

splitNearDist(input, near, sep = 1000, output = c("nearest", "matrix"))

Arguments

input	Spatial* object.
near	Spatial* object.
sep	Passed to seqSPDF(). Default set to 1000.
output	Return nearest distance or matrix of all combinations?

Details

This is a general wrapper for rgeos::gDistance() that allows for quicker nearer distance calculations and fixed a ram leak issue caused by large datasets when using the native rgeos function.

Value

Returns either a vector of the nearest distance of each input to the nearfeature or a matrix of all combinations.
