We're very glad that you followed us through all of the courses in this specialization. At this point, you've learned how to write R code and then how to wrap it into functions and packages. So, I think at this point, everybody has all the tools that they need to build their own R package. >> Absolutely, and I think this is a really exciting moment, because then now in the capstone project, we're going to be using all of these skills to kind of put together a real product that could be put out there for other people to use. And so we're going to be looking at data, we're going to be writing functions to kind of manipulate data. We're going to be making visualizations, and packaging it together with tutorials and documentation. And making sure that they pass all the appropriate checks to kind of be a coherent package for that other people to use and distribute through GitHub. So, it's really going to cover the whole breath of the specialization. And I think it's going to result to something that's really interesting. >> One of the best things about working in R is it's got a great community of people who develop packages, and I've benefited a lot from a lot of packages that are out there, and I bet you probably have too. >> Absolutely, yes. Yeah. >> And I enjoy writing my own, so I'm really hoping that we've given everybody the skills now where they can join that community, and start contributing their own work. >> Absolutely, and so, congratulations on making it to the capstone project. We're really looking forward to seeing what you can build.
