This is a simple wrapper around the geosphere function bearing to return the
bearing (in degrees relative to north) of lines.
Usage
line_bearing(l, bidirectional = FALSE)
Arguments
l
A SpatialLinesDataFrame
bidirectional
Should the result be returned in a bidirectional format?
Default is FALSE. If TRUE, the same line in the oposite direction would have the same bearing
Details
Returns a boolean vector. TRUE means that the associated line is in fact a point
(has no distance). This can be useful for removing data that will not be plotted.
