add_significance_stars: Add significance stars

Description

experimental Add significance stars to estimates with small p-values

Usage

add_significance_stars(
  x,
  pattern = "{estimate}{stars}",
  thresholds = c(0.001, 0.01, 0.05),
  hide_ci = TRUE,
  hide_p = TRUE,
  hide_se = FALSE
)

Arguments

x

a 'tbl_regression' or 'tbl_uvregression' object

pattern

glue-syntax string indicating what to display in formatted column. Default is "{estimate}{stars}". Other common patterns are "{estimate}{stars} ({conf.low}, {conf.high})" and "{estimate} ({conf.low} to {conf.high}){stars}"

thresholds

thresholds for significance stars. Default is c(0.001, 0.01, 0.05)

hide_ci

logical whether to hide confidence interval. Default is TRUE

hide_p

logical whether to hide p-value. Default is TRUE

hide_se

logical whether to hide standard error. Default is FALSE

Future Updates

There are planned updates to the implementation of this function with respect to the pattern= argument. Currently, this function replaces the numeric estimate column, with a formatted character column following pattern=. Once gt::cols_merge() gains the rows= argument the implementation will be updated to use it, which will keep numeric columns numeric. For the vast majority of users, the planned change will be go unnoticed.

Examples

# NOT RUN {
tbl <-
  lm(time ~ ph.ecog + sex, survival::lung) %>%
  tbl_regression(label = list(ph.ecog = "ECOG Score", sex = "Sex"))

# Example 1 ----------------------------------
add_significance_stars_ex1 <-
  tbl %>%
  add_significance_stars(hide_ci = FALSE, hide_p = FALSE)

# Example 2 ----------------------------------
add_significance_stars_ex2 <-
  tbl %>%
  add_significance_stars(
    pattern = "{estimate} ({conf.low}, {conf.high}){stars}",
    hide_ci = TRUE, hide_se = TRUE
  ) %>%
  modify_header(estimate ~ "**Beta (95% CI)**") %>%
  modify_footnote(estimate ~ "CI = Confidence Interval", abbreviation = TRUE)

# Example 3 ----------------------------------
# Use <br> to put a line break between beta and SE in HTML output
add_significance_stars_ex3 <-
  tbl %>%

    hide_se = TRUE,
