The plot command will try to produce the appropriate plots based on the data type. The data that is defined above, though, is numeric data. You need to convert the data to factors to make sure that the plot command treats it in an appropriate way. The as.factor command is used to cast the data as factors and ensures that R treats it as discrete. R makes it easy to combine multiple plots into one overall graph, using either the par or layout function. With the par function, you can include the option mfrow=c (nrows, ncols) to create a matrix of nrows x ncols plots that are filled in by row. Mfcol=c (nrows, ncols) fills in the matrix by columns. Is it possible to obtain 3 plots in a single figure in R with a distribution as shown in the image below? The plots must have the same width, and plot C should be centered.

Plot

The plot() function is used to draw points (markers) in a diagram.

The function takes parameters for specifying points in the diagram.

Parameter 1 specifies points on the x-axis.

Parameter 2 specifies points on the y-axis.

At its simplest, you can use the plot() function to plot two numbers against each other:

Example

Draw one point in the diagram, at position (1) and position (3):

To draw more points, use vectors:

Example

Draw two points in the diagram, one at position (1, 3) and one in position (8, 10):

Multiple Points

You can plot as many points as you like, just make sure you have the same number of points in both axis:

For better organization, when you have many values, it is better to use variables:

Sequences of Points

If you want to draw dots in a sequence, on both the x-axis and the y-axis, use the : operator:

Draw a Line

The plot() function also takes a type parameter with the value l to draw a line to connect all the points in the diagram:

Plot Labels

Line Plot In R

The plot() function also accept other parameters, such as main, xlab and ylab if you want to customize the graph with a main title and different labels for the x and y-axis:

Graph Appearance

There are many other parameters you can use to change the appearance of the points.

Colors

Multiple Plots In R

Use col='color' to add a color to the points:

Size

Use cex=number to change the size of the points (1 is default, while 0.5 means 50% smaller, and 2 means 100% larger):

Example

Point Shape

Use pch with a value from 0 to 25 to change the point shape format:

Example

The values of the pch parameter ranges from 0 to 25, which means that we can choose up to 26 different types of point shapes:
