gtsummary (version 1.6.3)

tbl_stack: Stacks two or more gtsummary objects

Description

Assists in patching together more complex tables. tbl_stack() appends two or more tbl_regression, tbl_summary, tbl_svysummary, or tbl_merge objects. Column attributes, including number formatting and column footnotes, are retained from the first passed gtsummary object.

Usage

tbl_stack(tbls, group_header = NULL, quiet = NULL)

Value

A tbl_stack object

Arguments

tbls

List of gtsummary objects

group_header

Character vector with table headers where length matches the length of tbls=

quiet

Logical indicating whether to print messages in console. Default is FALSE

Example Output

Example 1

Example 2
