## Introducing a scatter plot

Scatter plots are used primarily to conduct a quick analysis of the relationships among different variables in our data. It is simply plotting points on the x-axis and y-axis. Scatter plots help us detect whether two variables have a positive, negative, or no relationship. In this recipe, we will study the basics of plotting in R using scatter plots. The following screenshot is an example of a scatter plot:

### Getting ready

For implementing the basic scatter plot in R, we would use Carseats data available with the `ISLR`

package in R.

### How to do it…

We will also start this recipe by installing necessary packages using the `install.packages()`

function and loading the same in R using the `library()`

function:

install.packages("ISLR") library(ISLR)

Next, we need to load the data in R. Almost all R packages come with preloaded data and hence we can load the data only after we load the library in R. We can attach the data in R using the `attach()`

function. We can view the entire list...
