freqtable: Frequency table of variables

Description

Generate frequency tables for one or more variables in a data frame or a survey design.

Usage

freqtable(.data, ...)
# S3 method for default
freqtable(.data, ..., na.rm = FALSE, weights = NULL)
# S3 method for survey.design
freqtable(.data, ..., na.rm = FALSE, weights = TRUE)

Value

The result is an array of class `table`.

Arguments

.data

a data frame or `survey.design` object

...

one or more expressions accepted by select selecting at least one variable

na.rm

Whether to remove missing values in the variables.

Examples

data(hdv2003)
freqtable(hdv2003, nivetud, sport)
freqtable(hdv2003, nivetud, sport, sexe)
freqtable(hdv2003, nivetud, sport, weights=poids)
freqtable(hdv2003, starts_with("trav"))

# Using survey design objects
library(survey)
hdv2003_wtd <- svydesign(ids=~1, weights=~poids, data=hdv2003)
freqtable(hdv2003_wtd, nivetud, sport)

# Compute percentages based on frequencies
hdv2003 |> freqtable(sport) |> freq()
hdv2003 |> freqtable(sport, sexe) |> prop()
hdv2003 |> freqtable(sport, sexe) |> cprop()
