The application must include:
The code below is run within the Presentation.
column <- names(mtcars)
description <- c("Miles/(US) gallon","Number of cylinders","Displacement (cu.in.)",
"Gross horsepower","Rear axle ratio","Weight (1000 lbs)","1/4 mile time",
"Engine (0 = V-shaped, 1 = straight)","Transmission (0 = automatic, 1 = manual)",
"Number of forward gears","Number of carburetors")
table<-cbind(column,description)
The code below is then run on the following page.
kable(table)
The analysis is based on the mtcars dataset which has 11 columns/ variables as set out below. Any one of these can be selected as the outcome and then the Server code calculates the p-value for all the other variables as predictors. The lower the p-value, the greater the predictive nature of the variable.
A selectsize input widget is used to choose the Outcome and the values for this are calculated within the Server code.
| column | description |
|---|---|
| mpg | Miles/(US) gallon |
| cyl | Number of cylinders |
| disp | Displacement (cu.in.) |
| hp | Gross horsepower |
| drat | Rear axle ratio |
| wt | Weight (1000 lbs) |
| qsec | ¼ mile time |
| vs | Engine (0 = V-shaped, 1 = straight) |
| am | Transmission (0 = automatic, 1 = manual) |
| gear | Number of forward gears |
| carb | Number of carburetors |
The results are shown in tabular form and also a spider chart.
