rOpenSci is entirely a community driven effort. The project originally came together from conversations between like-minded researchers and continues to expand as more people contribute tools, expertise, and research ideas. It is a global community of researchers, students, software developers, and various others working towards improving the world of science. You are welcome to join us and help improve tools and practices available to researchers.
