Homework 5

You are currently in the GitHub repository (repo) for HW-5. You must have completed all the steps in Setting Up.

Example: Data Visualization

In 1999, Leland Wilkinson wrote the "Grammar of Graphics", laying out the proposed grammar to build statistical visualizations in the abstract (i.e. not specific to any programming language).
In 2005, Hadley Wickham created the ggplot2 package, which is an implementation in R of the grammar of graphics.

However, the grammar of graphics has been implemented elsewhere too

plotly is a web interface for creating graphics using the grammar.

Tableau is a proprietary (i.e. not open-source/free) software suite for data visualization.

In fact, Leland Wilkinson used to work at Tableau for many years, and his fingerprints are left all over it.

Produce two visualizations in Tableau based on two (out of the three) Excel spreadsheets and submit these.
As your are working, try to identify where the various components of data visualization and data manipulation we've covered lie.
The bar for grading is low. This HW is really about exploration, not getting "right answers".

Trying to emphasize: this is not a class on R; it is a class that uses R to implement bigger ideas.
The value of abstraction:
- Camera analogy
- Learning in the Liberal Arts
