Arguments

A data frame.

na.rm

A boolean specifying whether missing values (including NaN) should be removed.

pct

Details

The data frame can be grouped using dplyr::group_by() so that the number of observations will be calculated within each group level.

Examples

count_data(quote_source, source)
count_data(quote_source, source, sex)
count_data(quote_source, source, sex, na.rm = TRUE)
count_data(quote_source, source, sex, na.rm = TRUE, pct = TRUE)

# Use dplyr::group_by() to calculate proportions within a group
quote_source |>
  dplyr::group_by(source) |>
