freq {prettyR}R Documentation

Calculate a frequency table

Description

Calculates one or more frequency table(s) from a vector, matrix or data frame.

Usage

 freq(x,variable.labels=NULL,display.na=TRUE,bin.range=NULL,include.empty=FALSE)

Arguments

x a vector, matrix or data frame.
variable.labels optional labels for the variables. The default is the names of the variable passed or the names attribute if the variable has more than 1 dimension.
display.na logical - whether to display counts of NAs.
bin.range minimum and maximum of the desired range of integer values. Ignored if x is not numeric.
include.empty logical - whether to display empty bins.

Details

freq calls integer.frequency if x is numeric, otherwise table to get the frequency counts and builds a list with one or more components containing the value labels and counts.

Value

A list with one or more components. Each component includes the values of the relevant variable as the names.

Note

The limit on the number of bins has been removed, so passing a numeric vector with many levels may produce a huge, useless "frequency" table.
