Book Description
Turn your R code into packages that others can easily download and use. This practical book shows you how to bundle reusable R functions, sample data, and documentation together by applying author Hadley Wickham’s package development philosophy. In the process, you’ll work with devtools, roxygen, and testthat, a set of R packages that automate common development tasks. Devtools encapsulates best practices that Hadley has learned from years of working with this programming language. Ideal for developers, data scientists, and programmers with various backgrounds, this book starts you with the basics and shows you how to improve your package writing over time. You’ll learn to focus on what you want your package to do, rather than think about package structure. Learn about the most useful components of an R package, including vignettes and unit tests Automate anything you can, taking advantage of the years of development experience embodied in devtools Get tips on good style, such as organizing functions into files Streamline your development process with devtools Learn the best way to submit your package to the Comprehensive R Archive Network (CRAN) Learn from a well-respected member of the R community who created 30 R packages, including ggplot2, dplyr, and tidyr

Book Description
Python Packages introduces Python packaging at an introductory and practical level that’s suitable for those with no previous packaging experience. Despite this, the text builds up to advanced topics such as automated testing, creating documentation, versioning and updating a package, and implementing continuous integration and deployment. Covering the entire Python packaging life cycle, this essential guide takes readers from package creation all the way to effective maintenance and updating. Python Packages focuses on the use of current and best-practice packaging tools and services like poetry, cookiecutter, pytest, sphinx, GitHub, and GitHub Actions. Features: The book’s source code is available online as a GitHub repository where it is collaborated on, automatically tested, and built in real time as changes are made; demonstrating the use of good reproducible and clear project workflows. Covers not just the process of creating a package, but also how to document it, test it, publish it to the Python Package Index (PyPI), and how to properly version and update it. All concepts in the book are demonstrated using examples. Readers can follow along, creating their own Python packages using the reproducible code provided in the text. Focuses on a modern approach to Python packaging with emphasis on automating and streamlining the packaging process using new and emerging tools such as poetry and GitHub Actions.

Book Description
One of the greatest challenges facing package manufacturers is to develop reliable fine pitch thin packages with high leadcounts, capable of dissipating heat, and deliver them in volume to the market in a very short space of time. How can this be done? Firstly, package structures, materials, and manufacturing processes must be optimised. Secondly, it is necessary to predict the likely failures and behaviour of parts before manufacture, whilst minimising the amount of time and money invested in undertaking costly experimental trials. In a high volume production environment, any design improvement that increases yield and reliability can be of immense benefit to the manufacturer. Components and systems need to be packaged to protect the IC from its environment. Encapsulating devices in plastic is very cheap and has the advantage of allowing them to be produced in high volume on an assembly line. Currently 95% of all ICs are encapsulated in plastic. Plastic packages are robust, light weight, and suitable for automated assembly onto printed circuit boards. They have developed from low pincount (14-28 pins) dual-in-line (DIP) packages in the 1970s, to fine pitch PQFPs (plastic quad flat pack) and TQFPs (thin quad flat pack) in the 1980s-1990s, with leadcounts as high as 256. The demand for PQFPs in 1997 was estimated to be 15 billion and this figure is expected to grow to 20 billion by the year 2000.

Book Description
A sanitary inspection is a simple, on-site evaluation (traditionally using a checklist) to help identify and support the management of priority risk factors that may lead to contamination of a drinking-water supply. Sanitary inspections are a well-established and widely-applied practice. They can support water safety planning, and in some contexts, may be a simplified alternative to water safety plans. This publication presents the World Health Organization’s (WHO’s) sanitary inspection packages. These packages update the sanitary inspection forms in WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. With more than 25 years of practical experience with the application of sanitary inspections, these packages have been developed from a comprehensive evidence review and established good practices. Each package includes a sanitary inspection form, supported by technical guidance and management advice to help ensure the ongoing safe management of small water supplies. These new tools support proactive risk management and drinking-water quality surveillance across a broad range of water delivery scenarios, and can be applied by health authorities, surveillance agencies, water suppliers, and other stakeholders. As such, they are a valuable practical tool to help implement the recommendations in WHO’s 2024 Guidelines for drinking-water quality: small water supplies.
