get_step_average {capl}  R Documentation 
Compute average daily steps taken.
Description
This function computes the daily arithmetic mean of a week of steps taken as measured by a pedometer (step_average
). This variable is used to compute
the step score (step_score
).
Usage
get_step_average(raw_data = NULL)
Arguments
raw_data 
A data frame that includes seven days of pedometer steps and their corresponding on and off times. See Details for how these variables must be named. 
Details
This function will throw an error unless the following variables are found in the raw_data
argument:

steps1

steps2

steps3

steps4

steps5

steps6

steps7

time_on1

time_on2

time_on3

time_on4

time_on5

time_on6

time_on7

time_off1

time_off2

time_off3

time_off4

time_off5

time_off6

time_off7
There must be at least three valid days for an arithmetic mean to be computed. If only three valid days, one of the step values from a valid day will be randomly sampled and used for the fourth valid day before computing the mean.
Other capl
functions called by this function include: validate_steps()
and get_pedometer_wear_time()
.
Value
Returns a data frame with nine columns: steps1
(validated), steps2
(validated), steps3
(validated), steps4
(validated), steps5
(validated), steps6
(validated), steps7
(validated), valid_days
and step_average
. The steps are validated with the validate_steps()
function.
