plot_data: Plot accelerometer data for each day

Description

This function plots accelerometer data against time for each day of measurement, with the possibility to specify the metric to visualize.

Usage

plot_data(
  data,
  metric = "axis1",
  col_time = "time",
  col_nonwear = "non_wearing_count",
  col_wear = "wearing_count",
  zoom_from = "00:00:00",
  zoom_to = "23:59:59"
)

Value

A ggplot object.

Arguments

data

A dataframe obtained using the prepare_dataset and then the mark_wear_time functions.

metric

A character value to indicate the name of the variable to be plotted against time.

col_time

A character value to indicate the name of the variable to plot time data.

col_nonwear

A character value to indicate the name of the variable used to count nonwear time.

col_wear

A character value to indicate the name of the variable used to count wear time.

zoom_from

A character value with the HH:MM:SS format to set the start of the daily period to visualize.

zoom_to

A character value with the HH:MM:SS format to set the end of the daily period to visualize.

Examples

file <- system.file("extdata", "acc.agd", package = "activAnalyzer")
mydata <- prepare_dataset(data = file)
mydata_with_wear_marks <- mark_wear_time(
    dataset = mydata, 
    TS = "TimeStamp", 
    to_epoch = 60,
    cts  = "vm",
    frame = 90, 
    allowanceFrame = 2, 
    streamFrame = 30
    )
plot_data(
    data = mydata_with_wear_marks, 
    metric = "vm", 
    col_time = "time", 
    col_nonwear = "non_wearing_count", 
    col_wear = "wearing_count",
    zoom_from = "02:00:00",
    zoom_to = "23:58:00"
    )
