ard_regression_basic.R

#' Basic Regression ARD
#'
#' @description
#' A function that takes a regression model and provides basic statistics in an
#' ARD structure.
#' The default output is simpler than [`ard_regression()`].
#' The function primarily matches regression terms to underlying variable names
#' and levels.
#' The default arguments used are
#'
#' ```r
#' broom.helpers::tidy_plus_plus(
#'   add_reference_rows = FALSE,
#'   add_estimate_to_reference_rows = FALSE,
#'   add_n = FALSE,
#'   intercept = FALSE
#' )
#' ```
#'
#' @inheritParams ard_regression
#' @param stats_to_remove (`character`)\cr
#'   character vector of statistic names to remove. Default is
#'   `c("term", "var_type", "var_label", "var_class", "label", "contrasts_type", "contrasts", "var_nlevels")`.
#'
#' @return data frame
#' @name ard_regression_basic
#' @export
#'
#' @examplesIf do.call(asNamespace("cardx")$is_pkg_installed, list(pkg = "broom.helpers"))
#' lm(AGE ~ ARM, data = cards::ADSL) |>
