Description

Creates a data frame with a summary of descriptive information for each track

Usage

des_summary(tracks, cweight = "auto", cgaps = "", t_id = "id", des_df = "")

Arguments

tracks	psyo. Data frame with tracks.
cweight	character. Column name of tracks that contains the weight for the calculation.
cgaps	character. Column name of tracks that marks gaps with TRUE.
t_id	character or numeric. Column name in tracks that identifies the separate tracks.
des_df	data frame. Function results will be merge with this data frame.

Value

Data frame

id	id of the track
begin_time	begin time of the track
end_time	end time of the track
duration_in_mins	duration in minutes
tracker_interval_in_seconds	tracker interval in seconds
coordinates	number of coordinates without gaps
coordinates_gapped	number of coordinates with gaps
coordinates_all	number of all coordinates
time_duplicates	coordinates with the same time
time_gap	coordinates that are marked as gaps because they differ to much from the tracker interval
speed_gap	coordinates that are mark's as gaps because they have a higher speed than expected
sum_km	total number of kilometres
mean_kmh	average speed in kmh
mean_kmh_no_stop	average speed in kmh without coordinates with 0 speed
movement_time_sum	total time without speed higher than 0
no_movement_time_sum	total time with speed equal to 0
move_by_no_move_ratio	ratio between movement and no movement time
time_good_sum	data with good data
time_missing_sum	data that is missing
time_gap_sum	data that is excluded by gaps
