CONCLUSION

Conclusion

You should hopefully now be armed to face R without an ounce of fear in your soul! If you have followed attentively, you should be able to navigate and play with your data in R. You know how to perform basic statistical tests, and even plot beautiful graphs that match what you are trying to show. And thanks to this last course, you can even create functions to do the dirty work for you, without breaking a sweat! As importantly, if you should, you also know how to ask for help if you are stuck in R. And finally, if everything else fails, most R questions have been asked, and the answers can be found with Google, or directly through the CRAN website at https://cran.r-project.org/search.html or rseek.org

I hope that we managed together to cover the apparent “dryness” that R offers at first sight with a healthy layer of gravy, and that any reticence that might have existed prior to this course is now gone… Or, at least, the ones regarding R. I can’t do anything for you if you are reluctant to things like stinky French cheeses. Seriously, they’re like heaven on bread… if heaven were really filled with thousands of athletes’ stinky socks, but that’s not the question here.

Now, young grasshopper, go free and explore the amazing world of R and its ecosystem. Your journey is just starting, and will be full of adventures, occasional setbacks, but ultimately -hopefully- successful. Before taking your leave, if this site provided you with the tools you needed to reach enlightenment, and want to keep the lights on, and help me create new content for it, feel free to donate right here!

Thanks for coming, and enjoy your journey in R!!!
