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:
Plumbers, pipefitters, and steamfitters may use many different materials and construction techniques, depending on the type of project. Residential water systems, for example, use copper, steel, and plastic pipe that one or two plumbers can install. Power plant water systems, by contrast, are made of large steel pipes that usually take a crew of pipefitters to install. Some workers install stainless steel pipes on dairy farms and in factories, mainly to prevent contamination.

The Waterworks company came today to take care of some problem downspouts surrounding our home. Their technician, Dave, was professional and determined to get our lines clear. He worked hard to cable and clear out the spouts. He also provided great information and recommendations as to our options for areas with large tree roots. We were extremely happy with the work and grateful for his wealth of plumbing knowledge. If you ever find yourself in need of honest and thorough work, look no further than The Waterworks.

Plumbing reached its early apex in ancient Rome, which saw the introduction of expansive systems of aqueducts, tile wastewater removal, and widespread use of lead pipes. With the Fall of Rome both water supply and sanitation stagnated—or regressed—for well over 1,000 years. Improvement was very slow, with little effective progress made until the growth of modern densely populated cities in the 1800s. During this period, public health authorities began pressing for better waste disposal systems to be installed, to prevent or control epidemics of disease. Earlier, the waste disposal system had merely consisted of collecting waste and dumping it on the ground or into a river. Eventually the development of separate, underground water and sewage systems eliminated open sewage ditches and cesspools.
