<p>During the summer of 2020, I took six classes, one of which was a GIS course based in R. Out of the three coding classes I took this summer, this GIS course was the most hands-on and provided me with the most experience for data science. Below is a collection of links for all the projects that I completed.</p>

<ul>
<li>In this project, I learned how to utilize both Rmarkdown and Github Pages to author a static website</li>
<li>Helped me understand file paths and creating directories for raw data, images, Rmarkdown files, and R scripts</li>
<li>“Committing” files to git and “pushing” changes to GitHub</li>
<li>Includes a github repository for access to all the code</li>
<li>Learned how to display my work in a way that is visible to the public</li>

</center>
<ul>
<li>Learned the basics of data wrangling</li>
<li>Gained the ability to analyze data sets in order to be able to be able to identify important information as well as merge multiple data sets on recurring variables</li>
<li>Learned the basics of ggplot2 which allows me to present my data analysis through graphs and other visualizations</li>
<li>Helped me understand the importance of scale when graphing as two graphs with the same data can imply two very different results</li>
