In questionr: Functions to Make Surveys Processing Easier

Frequency table of variables

Description

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

Usage

freqtable(.data, ...)

## Default S3 method:
freqtable(.data, ..., na.rm = FALSE, weights = NULL)

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

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.
weights	If '.data' is a data frame, an optional expression selecting a weighting variable. If '.data' is a survey design, either 'TRUE' (the default) to to use survey weights, or 'FALSE' or 'NULL' to return unweighted frequencies.

Value

The result is an array of class 'table'.

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()
