Add N to regression table

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

# S3 method for 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.

...
