In meltt: Matching Event Data by Location, Time and Type

Performing iterative comparison and matching [Auxiliary Function]

Description

Auxiliary function that generates an R wrapper around the main python function used to process the numerical matrix generated in meltt. Returns a summary of matched entries.

Usage

meltt.match(data, twindow, spatwindow, smartmatch, certainty, k,
	    secondary, partial, weight, episodal, silent)

Arguments

data	numerical matrix passed from meltt.transform.
twindow	specification of temporal window in unit days passed from meltt.
spatwindow	specification of a spatial window in kilometers passed from meltt.
smartmatch	implement matching using all available taxonomy levels. When FALSE, matching will occur only on a specified taxonomy level passed from meltt.
certainty	specification of the the exact taxonomy level to match on when smartmatch = FALSE passed from meltt.
k	number of taxonomies passed from meltt.
secondary	vector of the number of taxonomy levels for each taxonomy passed from meltt.
partial	specifies whether matches along less than the full taxonomy dimensions are permitted. Passed from meltt.
weight	relative weight of each taxonomy in the calculation of the matching score. Passed from meltt.
episodal	boolean for wether normal or episodal matches are performed. Automatically determined and passed from meltt.
silent	Boolean specifying whether or not messages are displayed. Passed from meltt.

Details

Main auxiliary wrapper function that passes the processed data matrix from meltt to the python code used to manage the matching procedure.

Value

Returns a list object containing output of matching entries and a matrix of optimal selected matches.

Note

meltt.match requires the Python package NumPy to run. The package automatically checks whether NumPy is installed at runtime and returns an error if it is not.
