Today a user of my R package SixSigma
and reader of its motivating book, Six Sigma with R, made my day. The book was published in 2012 by Springer, and it was my first scientific publication (even before any article). Later (2015) Quality Control with R came with new and improved content.
Back to what I wanted to talk about: Paul, a user from a company in Germany, reported a “bug” in a function of the package. After telling him how I was going to solve it and some new plans to improve the whole thing, he gave me two senteces that encourage me to continue working on the topic:
- I use your package on daily basis, as user I really appreciate your work
- Regarding the book, I think it should be present in each personal library of a black belt
So, someone working in the “real world” uses on daily basis the open source software that one has developed, and says that your book should be a must for a black belt (see wikipedia for newcomers to Six Sigma). Sometimes one does things apparently nonsense, but later the reason appears.
Yeah, all right. It’s free software. I do not earn anything, beyond a few lines in the curriculum to fight in the academic career, and the satisfaction of doing things that serve society. Maybe I could be making more money. But what I would really like is to get funding to hire young researchers and take this development further and faster, so that we can bring these advances to companies nearby.
