tbl_merge: Merge tables

In gtsummary: Presentation-Ready Data Summary and Analytic Result Tables

Merge tables

Description

Merge gtsummary tables, e.g. tbl_regression, tbl_uvregression, tbl_stack, tbl_summary, tbl_svysummary, etc.

Usage

tbl_merge(tbls, tab_spanner = NULL)

Arguments

tbls	(list) List of gtsummary objects to merge
tab_spanner	(character) Character vector specifying the spanning headers. Must be the same length as tbls. The strings are interpreted with gt::md. Must be same length as tbls argument. Default is NULL, and places a default spanning header. If FALSE, no header will be placed.

Value

A 'tbl_merge' object

Examples

# Example 1 ----------------------------------
# Side-by-side Regression Models
library(survival)

t1 <-
  glm(response ~ trt + grade + age, trial, family = binomial) %>%
  tbl_regression(exponentiate = TRUE)
t2 <-
  coxph(Surv(ttdeath, death) ~ trt + grade + age, trial) %>%
  tbl_regression(exponentiate = TRUE)

tbl_merge(
  tbls = list(t1, t2),
  tab_spanner = c("**Tumor Response**", "**Time to Death**")
)

# Example 2 ----------------------------------
# Descriptive statistics alongside univariate regression, with no spanning header
t3 <-
  trial[c("age", "grade", "response")] %>%
  tbl_summary(missing = "no") %>%
  add_n() %>%
  modify_header(stat_0 ~ "**Summary Statistics**")
t4 <-
  tbl_uvregression(
    trial[c("ttdeath", "death", "age", "grade", "response")],
    method = coxph,
    y = Surv(ttdeath, death),
    exponentiate = TRUE,
    hide_n = TRUE
  )

tbl_merge(tbls = list(t3, t4)) %>%
  modify_spanning_header(everything() ~ NA_character_)
