Does anyone know the code to use in R programming to create a box plot?

Solutions

Expert Solution

The basic syntax to create a boxplot in R is −

boxplot(x, data, notch, varwidth, names, main)

Following is the description of the parameters used −

x is a vector or a formula.
data is the data frame.
notch is a logical value. Set as TRUE to draw a notch.
varwidth is a logical value. Set as true to draw width of the box proportionate to the sample size.
names are the group labels which will be printed under each boxplot.
main is used to give a title to the graph

EXAMPLE

We use the data set "mtcars" available in the R environment to create a basic boxplot. Let's look at the columns "mpg" and "cyl" in mtcars. The below script will create a boxplot graph for the relation between mpg (miles per gallon) and cyl (number of cylinders).

v Create a graph (either a histogram, box plot or stem and leaf plot … pick just one). Your graph could have either 5, 6 or 7 classes, depending on how you set it up. Create a table and list the class boundaries and the frequency in each class. You must explain to me in detail if you used fewer than 5 classes or more than 7 classes.
