get_activities: Extract active parts of dataframe

In VCCRI/CardiacProfileR: Generate Heart Rate Dynamic Profiles from TCX Data

Description

extracts parts of an energy dataframe that include an activity and resting at the start and end of activity

Usage

get_activities(energy_df, buffer_start, buffer_end, scale,
  time_threshold = 15, rest_threshold = 5, all_activities = TRUE)

Arguments

energy_df	An energy data frame as returned by load_tcx_file.
buffer_start	The number seconds before activity included in profile.
buffer_end	The number seconds after activity included in profile.
scale	The number of data points in each third of the final profile.
time_threshold	The minumum number of seconds duration for an activity.
rest_threshold	The maximum number of resting seconds within an activity.
all_activities	Find all the activities in a energy data frame, otherwise find only the first one.

Value

List of energy type data frames containing the activity, a buffer at the start and a buffer at the end See load_tcx_dir for a description of an energy dataframe.

See Also

load_tcx_dir for a description of an energy dataframe. all_start_end_points for a method to get the start and end points of all activities.

Other get activity functions: all_start_end_points, start_end_points

Examples

get_activities(df, 500, 500, 500)
get_activities(df, 200, 200, 1000, time_threshold = 60)
get_activities(df, 1500, 500, 100, rest_threshold = 10)
