hzar.map.latLong.dms: Convert D-M-S C strings to degrees

In hzar: Hybrid Zone Analysis using R

Description

Translate a character vector of typical map coordinate(s) to a matrix of numeric values.

Usage

hzar.map.latLong.dms(coordinates)

Arguments

coordinates

A character vector, with each string containing one or more latitude / longitude measurements, seperated by the cardinal direction of the measurement (N/S for latitude, E/W for longitude).

Value

A NxM matrix of numeric values, where N is the number of strings in coordinates and M is the greatest number of measurements in a single string. Each row contains the measurements from each string in coordinates, filling one column from left to right for each measurement. The remaining columns (if any) in a row have the value NA.
