The R Programming Language (R Core Team 2013) has become one of the most dominant programming languages for data analysis and visualization in recent years. At the same time, web services have become a common language for allowing various systems to interact with one another. The plumber R package (Trestle Technology, LLC 2017) allows users to expose existing R code as a service available to others on the Web. Plumber is best illustrated with an example:
I was looking for Dave Smith and Brandon Jones in here and I do not see their names. They both worked very hard and I was impressed by their team work.It was efficient until Brandon had an emergency and left Dave to do a two man job alone for the rest of the 2nd day. Dave was really committed to getting the the bathroom up and running for me each night before they left. I was pleased with their kindness in answering questions that I had while they were doing the work. I would call them again though I hope I don't need to.

Homes have many combustion appliances, such as stoves, water heaters, fireplaces, furnaces, and boilers. Without proper ventilation, these appliances can create harmful gases such as carbon monoxide. Adequate ventilation is absolutely necessary in any home. For example, exhaust fans can play a pivotal role in clearing out harmful gases in bathrooms, cooking areas, and garages. They can keep the air clear of harmful moisture and fumes, while increasing your comfort by keeping humidity levels low.
Plumbing originated during ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese cities as they developed public baths and needed to provide potable water and wastewater removal, for larger numbers of people. Standardized earthen plumbing pipes with broad flanges making use of asphalt for preventing leakages appeared in the urban settlements of the Indus Valley Civilization by 2700 BC. The Romans used lead pipe inscriptions to prevent water theft. The word "plumber" dates from the Roman Empire. The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes and some were also covered with lead. Lead was also used for piping and for making baths.
