I'm trying to figure out how to add customized options when using gtsummary--for example, stars for pvalues, captions, etc.
Here's a reproducible example using base mtcars data, in case that's more efficient...
library(tidyverse)
library(gtsummary)
#> Warning: package 'gtsummary' was built under R version 4.0.3
#> #Uighur
r1 <- lm(mpg ~ wt + cyl, data = mtcars) %>%
tbl_regression(exponentiate = TRUE)
r2 <- lm(hp ~ wt + cyl, data = mtcars) %>%
tbl_regression(exponentiate = TRUE)
r3 <- lm(qsec ~ wt + cyl, data = mtcars) %>%
tbl_regression(exponentiate = TRUE)
tbl_merge(list(r1, r2, r3),
tab_spanner = c("**MPG**", "**Horsepower**", "**Seconds**"))
You can use the add_significance_stars()
function to add stars to your estimates. To add titles and other formatting, convert the gtsummary object to gt with the as_gt()
function and add them using gt functions.
Example below.
library(gtsummary)
library(tidyverse)
packageVersion("gtsummary")
#> [1] '1.4.0'
# create a tibble with one row per model
tbl <-
tibble(outcome = c("mpg", "hp", "qsec")) %>%
rowwise() %>%
mutate(
tbl =
lm(str_glue("{outcome} ~ wt + cyl"), data = mtcars) %>%
tbl_regression() %>%
add_significance_stars(
hide_se = TRUE,
hide_ci = FALSE
) %>%
list()
) %>%
# pull tbl_regression() objects into single merged table
pull(tbl) %>%
tbl_merge(tab_spanner = c("**MPG**", "**Horsepower**", "**Seconds**")) %>%
# add table captions
as_gt() %>%
gt::tab_header(title = "Table 1. Car Regression Model",
subtitle = "Highly Confidential")
