gtsummary (version 1.2.1)

tbl_stack: Stacks two or more gtsummary regression objects

Description

Assists in patching together more complex tables. tbl_stack() appends two or more tbl_regression or tbl_merge objects. gt attributes from the first regression object are utilized for output table. If combining tbl_stack() and tbl_merge(), merge first then stack, or stack first and then merge.

Usage

tbl_stack(tbls)

Arguments

tbls

List of gtsummary regression objects

Value

A tbl_stack object

Example Output
