Adds labels describing the summary statistics presented for each variable in the tbl_summary / tbl_svysummary table.

add_stat_label(x, location = NULL, label = NULL)

Arguments

x	Object with class tbl_summary from the tbl_summary function or with class tbl_svysummary from the tbl_svysummary function
location	location where statistic label will be included. "row" (the default) to add the statistic label to the variable label row, and "column" adds a column with the statistic label.
label	a list of formulas or a single formula updating the statistic label, e.g. label = all_categorical() ~ "No. (%)"

Value

A tbl_summary or tbl_svysummary object

Example Output

Example 1

Examples

tbl <- trial %>%
  dplyr::select(trt, age, grade, response) %>%
  tbl_summary(by = trt)

# Example 1 ----------------------------------
# Add statistic presented to the variable label row
add_stat_label_ex1 <-
  tbl %>%
  add_stat_label(
    # update default statistic label for continuous variables
    label = all_continuous() ~ "med. (iqr)"
  )

# Example 2 ----------------------------------
add_stat_label_ex2 <-
  tbl %>%
  add_stat_label(
    # add a new column with statistic labels
    location = "column"
  )

# Example 3 ----------------------------------
add_stat_label_ex3 <-
  trial %>%
  select(age, grade, trt) %>%
  tbl_summary(
    by = trt,
    type = all_continuous() ~ "continuous2",
    statistic = all_continuous() ~ c("{mean} ({sd})", "{min} - {max}"),
  ) %>%
  add_stat_label(label = age ~ c("Mean (SD)", "Min - Max"))
