Ideal Car Selector App

An Overview by Z Ritchken

Summary of App

  1. App utilizes the "mtcars" Motor Trend dataset.
  2. Based on user inputs, outputs the most desirable car in the data set.
  3. Three separate dropdown inputs.

Definition of Inputs

  • Transmission Type: Manual or Automatic
  • Engine Type: 4, 6, or 8 cylinder engine
  • Acceleration versus Efficiency: User desires high acceleration versus efficiency

R Calculations

  • The app uses these primary functions to output desired vehicle:

-- Subset: Subsets mtcars data based on user input for tranmission type and engine.

-- Min and Max: Isolates minimum qsec variable for acceleration or maximum mpg variable for efficiency.

Further Development Opportunities

  • Expand dataset to include new 2015 model year cars.
  • Add in additional inputs including price, type of vehicle, and top speed.
  • Allow users to enter own inputs instead of dropdown list.
