Creating Plots Using Base Graphics in R: A Step-by-Step Tutorial

Find the diamonds data

In this section we will talk about the plot, for that we will use diamonds data set. This is very useful data set.

To understand this data set please run the below code. But you need to have to package installation "ggplot2". This package is required.

# Installation



install.packages("ggplot2")

require(ggplot2)

data(diamonds)


class(diamonds)


# understand the diamonds data set


help(diamonds)

See first 6 rows

head(diamonds)

Have a looks all the variable or columns

# A tibble: 6 x 10

Make histograms with base graphics

hist(diamonds$carat)



hist(diamonds$carat, main="Carat Histogram", xlab = "Carat")

Make scatterplots with base graphics

plot(diamonds$carat , diamonds$price)



# another way to do that


plot(price ~ carat, data = diamonds)



# label modification


plot(price ~ carat, data = diamonds, main = "Price vs Carat")

Make boxplots with base graphics

boxplot(diamonds$carat)
