gtsummary (version 1.6.1)

tbl_merge: Merge two or more gtsummary objects

Description

Merges two or more tbl_regression, tbl_uvregression, tbl_stack, tbl_summary, or tbl_svysummary objects and adds appropriate spanning headers.

Usage

tbl_merge(tbls, tab_spanner = NULL)

Arguments

tbls

List of gtsummary objects to merge

tab_spanner

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

Example Output

Example 1
