R – Data Visualization – boxplot

The boxplot() function – displays the center & spread of a numeric variable.

Shows the spread of the data, with median denoted by a solid black line.

boxplot(loadmycsv$Inventory)

boxplot(loadmycsv$Inventory, main=”My Chart”)

boxplot(loadmycsv$Inventory, main=”My Chart”,ylab=”Inventory (x10 lbs)”)

boxplot(loadmycsv$Price, main=”My Chart”,ylab=”Price ($$)”)

boxplot(csv$Price, main=”My Chart”,ylab=”Price ($$)”, xlab=”My x axis”)

R – Data Visualization – Histogram

The hist() function – displays the frequency of occurrence of a numeric value.

Shows the data in groups called as Bins.

hist(loadmycsv$Inventory)

hist(loadmycsv$Inventory, main=”My Chart”)

hist(loadmycsv$Inventory, main=”My Chart”,xlab=”Inventory (x10 lbs)”)

hist(loadmycsv$Price, main=”My Chart”,ylab=”Price ($$)”)

R – Data Visualization – plot/Scatterplot.

The plot() function – plots a 2 dimensional graph.

A Scatterplot shows bivariate relationship.

plot(x=MyDF_cust$age, y=MyDF_cust$SalesAmt, xlab = “Age”,ylab=“Income”)

Hands On – R Machine Learning Ex-8

Read the Customer_Age_Income.csv file in a dataframe MyDF_CAI.

Calculate standard deviation on the age.

Save the MyDF_cust dataframe as MyDF_cust.csv

Create Graphs for boxplot, histogram, and scatterplot for MyDF_CAI – age, income, SalesAmt.
