Package {StatisticTeach1}

Type: Package
Title: Interactive Tool for Statistics and Probability
Version: 0.1.1
Depends: R (≥ 4.1.0)
Description: A Shiny application designed to support the learning of basic concepts in statistics and probability. The tool provides an interactive interface that allows students to explore and visualize different statistical concepts intuitively, including descriptive statistics for continuous and qualitative variables, and probability distributions.

Frequency Table for Categorical Data

Description

Computes a frequency table for a categorical (factor) variable, including absolute frequency, cumulative frequency, relative frequency percentage, and cumulative relative frequency percentage.

Usage

ST_freq_factor(data, variable)

Arguments

data

A data.frame or tibble.

variable

Unquoted name of the column (factor) in data.

Value

A data.frame with five columns: Levels, Frequency, Cum.Frequency, Percent, and Cum.Percent.

Examples

ST_freq_factor(iris, Species)

Frequency Table for Continuous Data

Description

Computes a frequency table for a continuous (numeric) variable by dividing the data range into equal-width intervals (bins).

Usage

ST_freq_numeric(data, variable, bins = 5)

Arguments

data

A data.frame or tibble.

variable

Unquoted name of the numeric column in data.

bins

A positive integer giving the number of intervals into which the data range is divided. Defaults to 5.

Value

A data.frame with seven columns: lower, upper, midpoint, frequency, cumulative, freq_percent, and cum_percent.

Examples

ST_freq_numeric(mtcars, mpg, bins = 5)

Launch the StatisticTeach1 Shiny Application

Description

Opens the interactive Shiny interface for exploring descriptive statistics and probability distributions.

Usage

runStatisticTeach1(
  host = getOption("shiny.host", "127.0.0.1"),
  port = NULL,
  launch.browser = interactive()
)

Arguments

host

The IPv4 address that the application should listen on. Defaults to the shiny.host option, if set, or "127.0.0.1" otherwise.

port

The TCP port that the application should listen on. If NULL (the default) and the shiny.port option is set, that port will be used; otherwise a random available port is chosen.

launch.browser

Logical. If TRUE (the default in interactive sessions), the system default web browser is opened automatically after the app starts. Can also be a function that receives the application URL.

Value

No return value, called for its side effect of launching a Shiny application.

Examples

if (interactive()) {
  runStatisticTeach1()
}
