The "plot1.R", "plot2.R", "plot3.R", and "plot4.R" scripts are designed to create four PNG plots based on a dataset called "household_power_consumption.txt". This dataset is available compressed in zip format in this repository as "exdata-data-household_power_consumption.zip". Alternatively, the dataset can be downloaded here, also in zip format. Uncompressed, the dataset is 133MB. This dataset is from the “Individual household electric power consumption Data Set” from the UC Irvine Machine Learning Repository.
- The dataset must be uncompressed and named "household_power_consumption.txt"
- The dataset and R scripts must be in the same current working directory
