freq_format {freqtables}

Format freq_table Output for Publication and Dissemination

Description

The freq_format function is intended to make it quick and easy to format the output of the freq_table function for tables that may be used for publication. For example, a proportion and 95 could be formatted as "24.00 (21.00 - 27.00)."

Usage

freq_format(.data, recipe, name = NA, digits = NA)

Arguments

.data

A data frame of class "freq_table_one_way" or "freq_table_two_way".

recipe

A recipe used to create a new column from existing freq_table columns. The recipe must be in the form of a quoted string. It may contain any combination of column names, spaces, and characters. For example: "n (percent)" or "percent (lcl - ucl)".

name

An optional name to assign to the column created by the recipe. The default name is "formatted_stats"

digits

The number of decimal places to display.

Value

A tibble
