Calculate average bearing

Description

Calculate the average bearing, or direction of movement, for a movement path.

Usage

summaryAvgBearing(list, summary.df = NA)

Arguments

list

A list of data frames, each of which has a column for bearing.

summary.df

The summary data frame containing a column recording the bearing of each recorded movement.

Details

The bearing is the direction of movement and and falls between 0 and 360. Outdoors degree measures of 0/360 will typically correspond to due north. For servosphere data, 0/360 will correspond to the movement in the direction of the positive y-axis.

Value

A list of two named vectors. The first named vector contains the average bearing calculated for each movement path. The second named vector contains the rho, a measure of concentration for the average bearing.
