Creating an R dashboard

In this section, we create a dashboard in an R Notebook.

How to do it...

We have the following script; it loads and analyzes the data, producing four graphical elements. They are the head of the dataset, regression analysis, comparing sales components as drivers to sales, and comparing ad effectiveness:

 # Load and display same of the data points
 #install.packages("s20x", repos='http://cran.us.r-project.org')
 #install.packages("car", repos='http://cran.us.r-project.org')

 # libraries used
 library(s20x)
 library(car)

 # load and display data - originally at http://www.dataapple.net/wp-content/uploads/2013/04/
 df <- read.csv("grapeJuice.csv",header=T)
 head(df) 

# Calculate ad effectiveness
#
#divide the dataset into two sub dataset by ad_type
 sales_ad_nature = subset(df,ad_type==0)
 sales_ad_family = subset(df,ad_type==1)

# graph the two
 par(mfrow = c(1,2))

 hist(sales_ad_nature$sales,main="",xlab="sales with nature production theme ad",prob=T)
