R ScatterplotsThe scatter plots are used to compare variables. A comparison between variables is required when we need to define how much one variable is affected by another variable. In a scatterplot, the data is represented as a collection of points. Each point on the scatterplot defines the values of the two variables. One variable is selected for the vertical axis and other for the horizontal axis. In R, there are two ways of creating scatterplot, i.e., using plot() function and using the ggplot2 package's functions. There is the following syntax for creating scatterplot in R: Here,
Let's see an example to understand how we can construct a scatterplot using the plot function. In our example, we will use the dataset "mtcars", which is the predefined dataset available in the R environment. ExampleOutput: Scatterplot using ggplot2In R, there is another way for creating scatterplot i.e. with the help of ggplot2 package. The ggplot2 package provides ggplot() and geom_point() function for creating a scatterplot. The ggplot() function takes a series of the input item. The first parameter is an input vector, and the second is the aes() function in which we add the xaxis and yaxis. Let's start understanding how the ggplot2 package is used with the help of an example where we have used the familiar dataset "mtcars". ExampleOutput: We can add more features and make a more attractive scatter plots also. Below are some examples in which different parameters are added. Example 1: Scatterplot with groupsOutput: Example 2: Changes in axisOutput: Example 3: Scatterplot with fitted valuesOutput: Adding information to the graphExample 4: Adding titleOutput: Example 5: Adding title with dynamic nameOutput: Example 6: Adding a subtitleOutput: Example 7: Changing name of xaxis and yaxisOutput: Example 8: Adding themeOutput:
