For this assignment in ESM 262 Environmental Computing, we were asked to come up with a creative function, visualize the outputs, and then turn that function into a working package for public use. My partner and I created a function that conducts a sentiment analysis on lyrics for songs in the top 100. The required input is an artist name (e.g. Madonna), and the output is a data frame which contains a column for that artists’ Top 100 song titles and a column for the sentiment values for those songs.

This R package was designed to turn TIF files into animated GIF files. The unique part is the customization: users can select a prefix and/or suffix of the files they want to use (in case of mixed-contents folders), the speed of the GIF in frames per second, the output and input file paths, an output name (which gets combined with any given prefix or suffix), and the color palette to color the GIF with.
