Module 7: Adding Visual Analytics to an R Graph

 While the first graph made in R was made rather simply, this one required a bit more work in order to try to make the most out of the potential R has for visualizing information.

The code was written in mind to be able to accept a user's input, specifying the variables they want to compare in a visual representation. For example purposes, I overwrote the input to generate a bar plot comparing the miles per gallon a car is rated for compared to the number of cylinders in its engine. As we can see by the visual aid, the more cylinders a car has causes it to burn more fuel rather than cars with lesser amounts of cylinders. Few's recommendation on having data spread out so it's easier for the user to identify unique patterns in the visual aid plays off well in this example, though it could probably be improved by way of coloring each bar according to manufacturer, thereby adding an additional element to consider as well as better grouping the data together.

Module 6: Our First Graph

Image
 Rather than use base R syntax for making a chart, I opted instead to use ggplot2, as it provides more options and is something I'm much more comfortable with and understand better. This graph showcases the price trend of a certain video game over time since its release in 2007. Over time, the price per copy has fallen, and then steadily rose during the pandemic years. While Stephen Few argues for the notion that correlation does not equal causation, I believe the pandemic could certainly be theorized as a contributing factor for the sharp increase in price per copy.

LIS 4317 Final Project: R Chart showing Game Price changes over time

Image
 For this final project, I remembered the concept of used game prices tending to increase over time, especially older ones (more than 15 years old or so). With the lack on any decent visually-based references to measure the change in time these prices have had, I took it upon myself to make my own. Since no database I could find contained price listings, I obtained my own using PriceCharting.com. I selected a few random games released for the Nintendo GameCube, and recorded the price listing for "loose" games (only the disc). I then compiled all of the prices into an Excel CSV and imported it into RStudio. For clarification, the games I chose were (from left to right): Sonic Classics Collection Need For Speed: Most Wanted Shrek: Extra Large SpongeBob Squarepants: Battle For Bikini Bottom Lego Star Wars: The Video Game Super Monkey Ball TimeSplitters 2 Turok: Evolution Geist Batman: Dark Tomorrow Donkey Kong Jungle Beat I then made a ggplot function that would allow me to easi...

Final Project: DescribeR v1.0.0

 After some time, I'm thrilled to finally release the source code for my first ever R package. Alongside the first three functions I described in the original description file, I've also added an additional interactive_heatmap function that can create heatmaps of correlating numerical data in a given dataset. It's my hope that this package will make exploratory analysis easier for those dealing with unfamiliar sets of data, leaving more time to figure out more advanced uses for said data.
