Continuous Summary Table Bridges

Bridge function for converting tbl_continuous() cards to basic gtsummary objects. This bridge function converts the 'cards' object to a format suitable to pass to brdg_summary(): no pier_*() functions required.

Usage

brdg_continuous(cards, by = NULL, statistic, include, variable, type)

Arguments

cards

(card)
An ARD object of class "card" typically created with cards::ard_*() functions.

by

(string)
string indicating the stratifying column

statistic

(named list)
named list of summary statistic names

include

(tidy-select)
Variables to include in the summary table. Default is everything().

variable

(tidy-select)
A single column from data. Variable name of the continuous column to be summarized.

type

(named list)
named list of summary types

Value

a gtsummary object

Examples

library(cards)

bind_ard(
  # the primary ARD with the results
  ard_summary(trial, by = grade, variables = age),
  # add missing and attributes ARD
  ard_missing(trial, by = grade, variables = age),
  ard_attributes(trial, variables = c(grade, age))
) |>
  # adding the column name
  dplyr::mutate(
    gts_column =
      ifelse(!context %in% "attributes", "stat_0", NA_character_)
  ) |>
  brdg_continuous(
    variable = "age",
    include = "grade",
    statistic = list(grade = "{median} ({p25}, {p75})"),
    type = list(grade = "categorical")
 ) |>
