# Rotate Axis Labels of Base R Plot (3 Examples)

In this article, I’ll explain how to **rotate axis labels of a Base R plot** in the R programming language.

The content of the post is structured as follows:

- Example Data
- Example 1: Rotate Axis Labels Horizontally
- Example 2: Rotate Axis Labels Perpendicular to the Axis
- Example 3: Rotate Axis Labels Vertically
- Video, Further Resources & Summary

Let’s get started…

## Example Data

In the examples of this R tutorial, we’ll use the following example data:

set.seed(77777) # Create example data x <- rnorm(1000) y <- rnorm(1000) |

set.seed(77777) # Create example data x <- rnorm(1000) y <- rnorm(1000)

The default plot looks as follows:

plot(x, y) # Default plot - parallel to the axis |

plot(x, y) # Default plot - parallel to the axis

**Figure 1: Base R Plot with Default Specifications.**

The axis labels of the x-axis have a horizontal orientation and the y-axis labels have a vertical orientation.

## Example 1: Rotate Axis Labels Horizontally

In order to change the angle of the axis labels of a Base R plot, we can use the las argument of the plot function. If we want to rotate our axis labels to a horizontal position, we have to specify las = 1:

plot(x, y, las = 1) # Horizontal labels |

plot(x, y, las = 1) # Horizontal labels

**Figure 2: Horizontal Angle of Axis Labels.**

Note that we can modify the las argument in any kind plot of Base R. In this example, we illustrated the las argument based on a scatterplot. However, we could also apply this R syntax for a barplot, histogram, boxplot, and so on…

## Example 2: Rotate Axis Labels Perpendicular to the Axis

If we want to show our axis labels in a perpendicular angle to the Axis, we have to specify las = 2:

plot(x, y, las = 2) # Perpendicular to the axis |

plot(x, y, las = 2) # Perpendicular to the axis

**Figure 3: Labels Perpendicular to the Axis.**

## Example 3: Rotate Axis Labels Vertically

For vertical axis labels, we need to specify las = 3:

plot(x, y, las = 3) # Vertical labels |

plot(x, y, las = 3) # Vertical labels

**Figure 4: Vertical Angle of Axis Labels.**
