# Break Axis of Plot in R (2 Examples)

In this tutorial, I’ll demonstrate how to cut out a part of the axis of a graphic in R.

Let’s jump right to the examples!

## Example Data

The following data will be used as basement for this R tutorial:

```x <- 1:100                         # Create example data
y <- 1:100```

As you can see, our data consists of two numeric vectors both ranging from 1 to 100.

Now, we can draw our data as shown below:

`plot(x, y)                         # Regular plot of example data` In Figure 1 it is shown that we have plotted a scatterplot of our entire data set.

## Example 1: Break Y-Axis of Plot Using gap.plot() Function of plotrix Package

Example 1 demonstrates how to remove a particular part of the y-axis from our plot.

For this, we can use the functions of the plotrix package. We first have to install and load plotrix:

```install.packages("plotrix")        # Install & load plotrix
library("plotrix")```

Next, we can use the gap.plot function to insert an axis break in our graph:

```gap.plot(x, y,                     # Apply gap.plot function
gap = c(10, 50))``` As shown in Figure 2, we have managed to create a gap between the values 10 and 50 on the y-axis of our graphic by executing the previous R programming syntax.

## Example 2: Break X-Axis of Plot Using gap.plot() Function of plotrix Package

Example 2 explains how to add a break on the x-axis of our plot.

For this, we have to set the gap.axis argument to be equal to “x”.

```gap.plot(x, y,                     # Apply gap.plot function
gap = c(10, 50),
gap.axis = "x")``` As shown in Figure 3, the previously shown R syntax has created a plot with break on the x-axis.

In summary: At this point you should know how to remove the middle of the plot area in R. Let me know in the comments section, in case you have any further comments or questions.
