ToyotaSiennaGasMileage

ToyotaSiennaGasMileage provides gas consumption data on a 2011 Toyota Sienna XLE from purchase through today. The data are available for those who are studying gas consumption, but also available for anybody interested in plotting or modeling a time series with irregular observations.

Data were originally recorded by hand. These sheets were scanned and digitized into csv files that match the scanned sheets. An R script is used to combine all the files into a single R data.frame included in the package as ToyotaSiennaGasMileage. Thus, these files provide an example data management process for manually recorded data.
