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 wanted to let you know that we were extremely happy with our first encounter with Pro-Service Plumbing. I called this morning and Kelly was extremely courteous and helpful. She had Jeromie at our house within two hours! Not only did he complete the job in record time but he discovered that the previous plumber we had out yesterday (who told us that we had a broken pipe on our main line) had misdiagnosed the problem. The first plumber said they were ordering parts and told us it could not be repaired until next week. They were going to charge us over $800.00 for a loose connection issue. Meanwhile, our front yard was flooding. Pro-Service fees were fair and reasonable. You will be our “go-to” plumbers from now on. Thank you!
Jeromie replaced our water heaters a week ago. Apparently some debris got in the line which clogged the kitchen faucet. Jeromie and Joe worked for a long time to completely disassemble the faucet to clear the problem. When that did not correct the problem it took a call to the manufacturer to find a hidden backflow valve that was dirty and causing the problem . I want to acknowledge Jeremy’s positive attitude and tenacity to arrive at a successful conclusion. Thank you for a job well done.
While it’s their job to make sure your pipes work like a well-oiled machine, it’s not their job to rebuild the wall they had to demolish to make that happen. So, while you’re going to get that water problem fixed, you’ll want to discuss in detail what kind of “mess” they might leave behind prior to the start of the project so you can plan accordingly. Remember, there are some jobs you can do yourself. Here’s how to solder copper pipe joints!
I guess all good things must come to an end. After a few good experiences we scheduled them again for the annual snaking of the drain. The first appointment they cancelled a couple of hours before the appointment, they said they were stuck at another job - it happens. Rescheduled for a few days later, they showed up and said they would not move the appliances to get to the sewage line [they always did this in the past]. Then they said only Mike could move appliances. So we rescheduled for when Mike got back from vacation. Then just before Mike was supposed to show up, Mike called and said he wouldn't move appliances anymore either. Thanks for jerking us around for 2 weeks.
Despite the Romans' common use of lead pipes, their aqueducts rarely poisoned people. Unlike other parts of the world where lead pipes cause poisoning, the Roman water had so much calcium in it that a layer of plaque prevented the water contacting the lead itself. What often causes confusion is the large amount of evidence of widespread lead poisoning, particularly amongst those who would have had easy access to piped water. This was an unfortunate result of lead being used in cookware and as an additive to processed food and drink, for example as a preservative in wine. Roman lead pipe inscriptions provided information on the owner to prevent water theft.
