Hello, reviewers! Here's how the code in this repository works.
- Download the Electric power consumption dataset, and unzip it.
- Move the file called household_power_consumption.txt into this Git checkout directory.
- Rather than trying to load such a large file into memory all at once in R, I wrote a very small Python script that filters the full dataset down to just the two days 01/02/2007 and 02/02/2007. To run this script (assuming you have Python installed), do
python reduce_dataset.py. - In case you don't have Python installed, I also included the resulting output file ("just_two_days.txt") in this repository. The rest of my scripts depend on having it available.
- The scripts plot1.R, plot2.R, plot3.R, and plot4.R generate the four chars. To run them all, simply start R and then do:
`
source('plot1.R')
source('plot2.R')
source('plot3.R')
source('plot4.R') `
