## S3 method for class 'tbl_regression'
add_n(x, location = NULL, ...)

## S3 method for class 'tbl_uvregression'
add_n(x, location = NULL, ...)

Arguments

x	a tbl_regression or tbl_uvregression table
location	location to place Ns. When "label" total Ns are placed on each variable's label row. When "level" level counts are placed on the variable level for categorical variables, and total N on the variable's label row for continuous.
...	Not used

Example Output

Example 1

Example 2

Examples

# Example 1 ----------------------------------
add_n.tbl_regression_ex1 <-
  trial %>%
  select(response, age, grade) %>%
  tbl_uvregression(
    y = response,
    method = glm,
    method.args = list(family = binomial),
    hide_n = TRUE
  ) %>%
  add_n(location = "label")

# Example 2 ----------------------------------
add_n.tbl_regression_ex2 <-
  glm(response ~ age + grade, trial, family = binomial) %>%
  tbl_regression(exponentiate = TRUE) %>%
  add_n(location = "level")
