Introduction

This is an application that loads Motor Trend's Car Data (mtcars) and allows a person to compare two cars against each other using the UI rather than a command line.

Side panel

The side panel allows you to pick two cars, an attribute to plot. Click on the Submit button to have the application show you the comparison of both cars.

Main panel

The main panel shows you what cars that you have selected and also shows the various attributes for each car such as mpg, cylinders, horsepower, etc.

For example:

# show two cars
data(mtcars)
mtcars$names <- rownames(mtcars)
f <- c("Datsun 710", "Valiant")
filter(mtcars, names %in% f)

##    mpg cyl disp  hp drat   wt  qsec vs am gear carb      names
## 1 22.8   4  108  93 3.85 2.32 18.61  1  1    4    1 Datsun 710
## 2 18.1   6  225 105 2.76 3.46 20.22  1  0    3    1    Valiant

Thank you

Thank you for using this application. I am sure that you will agree that for the non-R programmer this is a much easier way of comparing two cars against each other.
