Reclass columns of a data frame to match classes specified in a metadata dictionary

Usage

reclass(
  x,
  dict,
  use_factors = FALSE,
  value_labs = TRUE,
  header_labs = FALSE,
  times_chron = TRUE,
  fn_dates = parse_date,
  fn_dates_args = list(orders = c("Ymd", "dmY")),
  fn_datetimes = lubridate::parse_date_time,
  fn_datetimes_args = list(orders = c("Ymd HMS", "Ymd HM"))
)

Arguments

x: A data frame representing a REDCap form
dict: A metadata dictionary
use_factors: Logical indicating whether categorical REDCap variables (radio, dropdown, yesno, checkbox) should be returned as factors. Factor levels can either be raw values (e.g. "0"/"1") or labels (e.g. "No"/"Yes") depending on arguments value_labs and checkbox_labs. Defaults to FALSE.
value_labs: Logical indicating whether to return value labels (TRUE) or raw values (FALSE) for categorical REDCap variables (radio, dropdown, yesno, checkbox). Defaults to TRUE to return labels.
header_labs: Logical indicating whether to export column names as labels (TRUE) or raw variable names (FALSE). Defaults to FALSE to return raw variable names.
times_chron: Logical indicating whether to reclass time variables using chron::times (TRUE) or leave as character HH:MM format (FALSE). Defaults to TRUE. Note this only applies to variables of REDCap type "Time (HH:MM)", and not "Time (MM:SS)".
fn_dates: Function to parse REDCap date variables. Defaults to parse_date, an internal wrapper to lubridate::parse_date_time. If date variables have been converted to numeric (e.g. by writing to Excel), set to e.g. lubridate::as_date to convert back to dates.
fn_dates_args: List of arguments to pass to fn_dates. Can set to empty list list() if using a function that doesn't take any arguments.
fn_datetimes: Function to parse REDCap datetime variables. Defaults to lubridate::parse_date_time.
fn_datetimes_args: List of arguments to pass to fn_datetimes. Can set to empty list list() if using a function that doesn't take any arguments.
