od_coords2line: Convert origin-destination coordinates into desire lines

Description

Convert origin-destination coordinates into desire lines

Usage

od_coords2line(odc, crs = 4326, remove_duplicates = TRUE)

Arguments

odc

A data frame or matrix representing the coordinates of origin-destination data. The first two columns represent the coordinates of the origin (typically longitude and latitude) points; the third and fourth columns represent the coordinates of the destination (in the same CRS). Each row represents travel from origin to destination.

crs

A number representing the coordinate reference system of the result, 4326 by default.

remove_duplicates

Should rows with duplicated rows be removed? TRUE by default.
