 So my favorite free software project is R. I was first introduced to R and started working with it in my first semester as a biology student. I love working with the software. It makes it very easy and accessible to work with your own data and do statistical analysis. I'm still a student but I have already done a little bit of emulating my own data and analysing it with R. It's really great and I think it's a very important software as well for ecological studies for example, which nowadays is very important. So I would like to thank everyone who has been working on and developing packages. R is great.
