In Observation: Collect and Process Physical Activity Direct Observation Data

Manually Collect Direct Observation Data

Description

Manually Collect Direct Observation Data

Usage

manual_data_collection_program(
  id,
  timestamps,
  activities,
  durations = NULL,
  seated = NA,
  large_muscles_moving = NA,
  slow = NA,
  slowed_by_resistance = NA,
  ambulation = NA,
  light_walking = NA
)

Arguments

id	Character scalar giving ID to assign to the trial
timestamps	Vector of times (character or POSIX) corresponding to onset of each activity and (if durations = NULL) offset of the final activity (i.e., ending time of the trial)
activities	Character vector of activities in the sequence they were performed
durations	Optional numeric vector giving duration of each activity, in seconds
seated	Character vector giving yes/no/NA response for whether the participant was seated during each activity
large_muscles_moving	Character vector giving yes/no/NA response for whether the participant was moving large muscles during each activity
slow	Character vector giving yes/no/NA response for whether muscle contractions were slow during each activity
slowed_by_resistance	Character vector giving yes/no/NA response for whether slow muscle contractions were slowed because of resistance
ambulation	Character vector giving yes/no/NA response for whether the each activity is ambulatory
light_walking	Character vector giving yes/no/NA response for whether ambulation was slow enough to be considered light activity instead of moderate or vigorous

Value

A dataframe of pre-processed direct observation data generated from minimal input

Note

By default, activity duration is automatically calculated, which is accomplished via diff.POSIXt and thus requires n + 1 timestamps, where n is the number of activities. Alternatively, durations can be manually specified via the durations parameter, in which case only n timestamps are needed, corresponding to the onset of each activity.
