average_duplicates: Correct coordinates with the same time

In psyosphere: Analyse GPS Data

Description

Correct coordinates with the same time by replacing with one coordinate with a geomean position.

Usage

average_duplicates(tracks, t_id = "id")

Arguments

tracks	psyo. Data frame with tracks.
t_id	character or numeric. Column name in tracks that identifies the separate tracks.

Value

psyo

# Calculate mean position
psyo <- average_duplicates(psyo)

# Plot mean position
