Hi!

Thanks for visiting my sponsor page! It's great that you want to help contribute to the open source community!

Your contribution will help everyone continue to do awesome data science using R packages like quantmod, TTR, xts, IBrokers, and microbenchmark. It will also help me continue to contribute to many other packages, like quantstrat, blotter, PerformanceAnalytics, DEoptim, and zoo.

Maybe you've thought about how great it is to have all these tools, and you wanted to give back, but you weren't sure how to help. Open source isn't only about code, pull requests, and documentation. It's about people. Your sponsorship doesn't only help me. It also helps users of the hundreds of packages that depend on the packages I maintain and contribute to.

I work on open source because I love helping our community. I started maintaining quantmod, xts, and IBrokers when Jeff Ryan started a job that restricted his open source contributions. I started maintaining Olaf Mersmann's excellent microbenchmark package for the same reason.

I usually work on open source before I leave for my day job, and on weekend mornings before my 3 kiddos wake up. Your generous sponsorship helps me continue to support the community in the wee hours of the morning!

One last thing. Could you do me a favor if you use my packages at your job? I would really appreciate if you asked your company to become a sponsor. I know it's a bit of work, but it could make a big difference!

Thank you!
