Blog Logo

Welcome to my new website/blog. I am aiming to highlight some of the R packages that I have created. You can see a list of all the R packages I have in development and also see the source code on github here: R packages. In addition, I’ll likely talk about various topics with statistics, teaching, research, or R in general.

For my first post, I want to highlight my code to generate my blog logo. The code took a lot of trial and error and definitely is dependent on the size of the image file that is outputted. By far the most difficult part of the logo was the R logo, specifically the grey oval of the R logo. I tried to get the oval to change sizes at the correct point and to do this I created a size variable in my data.frame and passed this variable to ggplot2 to make the size change. It isn’t perfect, but is a bit unique.

The next logo I need to develop is my favicon.ico. Send me suggestions in the comments of this post.
