An Interactive Introduction to Life Data Analysis

An interactive introduction to Life Data Analysis that depends on 'WeibullR' by David Silkworth and Jurgen Symynck (2022) < https://CRAN.R-project.org/package=WeibullR>, a R package for Weibull Analysis, and 'learnr' by Garrick Aden-Buie et al. (2023) < https://CRAN.R-project.org/package=learnr>, a framework for building interactive learning modules in R.

WeibullR.learnr: An Interactive Introduction to Life Data Analysis

Welcome to WeibullR.learnr! This package contains a set of interactive learning modules for life data analysis, focusing on reliability, availability, and maintainability (RAM). It is designed for beginners, including university students and early-career professionals.

Motivation

Life data analysis is the study of how systems function over time, from machines to people. While various learning resources exist, many rely on proprietary software that can be inaccessible to students and early-career professionals.

WeibullR.learnr [@WeibullRlearnr] is an open-source collection of interactive learning modules, exercises, and functions designed for introductory life data analysis. The primary goal of this project is to introduce fundamental concepts while providing an open-source alternative for analyzing life data.

Installation Instructions

WeibullR.learnr is written in R and is built using WeibullR by David Silkworth and Jurgen Symynck (2022), a R package for Weibull Analysis, and learnr by Garrick Aden-Buie et al. (2023), a framework for building interactive learning modules in R.

To install WeibullR.learnr in R:

install.packages('WeibullR.learnr')

To install the development version:

devtools::install_github('paulgovan/weibullr.learnr')

Usage

Currently, three primary learning modules exist. These modules can be taken in either order and can be taken separately or together. The learning modules are designed to be plug-and-play, but changes can be made by forking the software repository and modifying the fork.

• WeibullR.learnr() - An interactive introduction to Life Data Analysis (estimated duration ~2 hours)
• RAMR.learnr() - A quick reference for common Reliability, Availability, and Maintainability concepts (estimated duration ~ 1 hour)
• TestR.learnr()- An interactive introduction to Reliability Testing (estimated duration ~ 2 hours)

The modules can also be accessed in a browser at WeibullR.learnr and RAMR.learnr, TestR.learnr

Several helper functions for common RAM calculations are also included:

• rel() - reliability function
• avail() - availability function
• mttf() - mean time to failure
• mtbf() - mean time between failure
• serv() - serviceability factor
• fr() - failure rate
