splitClip: Fast Clip for Spatial* objects.

In jacpete/jpfxns: JP Functions

Description

splitClip splits a Spatial* object from the (sp) package using seqSPDF, and runs rgeos::gIntersection() on the list.

Usage

splitClip(input, clipFeature, sep = 1000)

Arguments

input	Spatial* object.
clipFeature	SpatialPolygons* object.
sep	Passed to seqSPDF(). Default set to 1000.

Details

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

Value

Returns the true clip of a Spatial* feature.

Warning

Will not output with a dataframe due to limitations of the rgeos functions. Will look into using raster::intersection() in a future release.
