Standardize the Accelerometry Data

Usage

acti_standardize_data(
  data,
  subset_xyz = TRUE,
  colname_time = "time",
  lower_case = FALSE,
  check_xyz = TRUE
)

acti_standardise_data(
  data,
  subset_xyz = TRUE,
  colname_time = "time",
  lower_case = FALSE,
  check_xyz = TRUE
)

Arguments

data: A `data.frame` with a column for time in `POSIXct` (usually `time`), and `X`, `Y`, `Z`
subset_xyz: should only the `time` (if available) and `XYZ` be subset?
colname_time: column name of header for time
lower_case: flag to make sure all columns are lower case.
check_xyz: Check if X/Y/Z is in the data

Value

A `data.frame` with `X/Y/Z` and a time in `time` (if available).
