<p>Today starts my attempt at sharing my R journey with the world! I have been learning R off and on now since late 2019, I have begun to take it much more serious as I work through my Data Analytics class at UCF. My love for all things numbers and graphs has really blossomed, and I am choosing to share that love with anyone who cares to read. I will not claim to be the best at R, or any programming for that matter, but these are my attempts. Each post in this serious will be replicated a graph created in Tableau from the book Tableau for Healthcare. Todays graph is a simple horizontal bar chart, in transferring to both a new blog site and computer I have unfortunately lost the original bar graph, but trust me the one I created looks just like it.</p>
