tabfreq.leem: Frequency distribution table

In leem: Laboratory of Teaching to Statistics and Mathematics

Frequency distribution table

Description

Allows you to tabulate continuous and categorical data (quantitative or qualitative) in frequency distribution. Depending on the nature of the data, they can be grouped into class ranges or not.

Usage

## S3 method for class 'leem'
tabfreq(
  data,
  k = NULL,
  na.rm = FALSE,
  ordered = NULL,
  namereduction = TRUE,
  ...
)

Arguments

data	R object (data structure vector) of class leem. Use new_leem() function.
k	Number of classes. Default is NULL.
na.rm	a logical evaluating to TRUE or FALSE indicating whether NA values should be stripped before the computation proceeds.
ordered	Ordered vector of the same length and elements of data object. Default is NULL.
namereduction	Logical argument. If TRUE (default), the group names are reduzed the 10 characters. If FALSE, otherwise.
...	further arguments passed to or from other methods.

Value

The result of tabfreq() is a list. This list has two elements: table and statistics. The first is the data frequency table, and the second represents some useful statistics for methods of leem class.

Examples

# Example 1
library(leem)
x <- rbinom(36, 10, 0.6)
x <- new_leem(x, variable = "discrete")
tabfreq(x)

# Example 2 (Pipe operator)
rnorm(36, 100, 4) |>
  new_leem(variable = "continuous") |> tabfreq()

# Example 3
x <- rbinom(36, 10, 0.6)
# Constructor (object of leem class)
x <- new_leem(x, variable = "discrete")
tab <- tabfreq(x)
# Details
tab$table
tab$statistics

# Example 3 - ordered categories ("d","a", "b", "c")
w <- rep(letters[1:4], 1:4)
w |> new_leem(variable = "discrete") |> tabfreq(ordered = c("d","a", "b", "c"))
