This repo contains the four R code files and associated data plots for the Project 1 assignment of Exploratory Data Analysis.
Information used to produce the grids can be obtained online. For this work, the datafile has been condensed down into a smaller working file, and thus the full datafile is not needed to repoduce the experiement. A complete description of the data can be found at the UCI web site.
The script generate_datafile.R can be used to subset the data for the specific dates of [1,2] Feburary 2007. This smaller working datafile can easily be read into the scripts and generate the plots.
A copy of the working datafile is included in this repository, but can be regenerated by downloading the source datafile, extracting the archive, and running the generate_datafile.R in the same directory. The script will produce an outputfile named project1_datafile.Rda.
Each of the R code files are self-contained - there should be no need to load additional libraries or source utility resources. Each script loads the working datafile and outputs a PNG graphic similarly named but with a .png extension.
