If you want to check out the code for the app please check: https://github.com/rafaelmarino/carComparison
-This Shiny app utilizes the mtcars dataset from R to compare the features of any
2 given car models.
-This way, you can quickly compare between two cars things such as, which one has better miles per gallon, or more cylinders, or which of the 2 cars has more horsepower.
-You can see all 11 features compared next to each other neatly in a table.
-For further help please access the “Documentation” tab within the app.
-This App is a must have for the car enthusiast that wants more knowledge about this particular group of cars from 1973 or 1974.
-It's even more important if you're a car collector that likes to buy old cars and fine tune them.
-If you care about things like miles per gallon (mpg), nmber of cylinders (cyl) and gross horsepower (hp), this app provides you with a fast way to compare between different cars.
The data was extracted from the 1974 Motor Trend US magazine, and comprises fuel consumption and 10 aspects of automobile design and performance for 32 automobiles (1973-74 models). The features are:
[, 1] mpg Miles/(US) gallon;
[, 2] cyl Number of cylinders;
[, 3] disp Displacement (cu.in.);
[, 4] hp Gross horsepower;
[, 5] drat Rear axle ratio;
[, 6] wt Weight (lb/1000);
[, 7] qsec ¼ mile time;
[, 8]vs V/S; [, 9] am Transmission;
[,10] gear Number of forward gears;
[,11] carb Number of carburetors
-Step 1: Select “Toyota Corolla” on the first Input Box.
-Step 2: Select “Datsun 710” on the second Input Box.
-Step 3: See the results on the right.You can see a short version of the comparison below:
mpg cyl disp hp drat wt
Toyota Corolla 33.9 4 71.1 65 4.22 1.835
Datsun 710 22.8 4 108.0 93 3.85 2.320
If you care about mpg then you definitely need to get the Toyota Corolla over the Datsun!
