# Absolute Value in R (Example)

This article shows how to apply the abs() function in order to compute the absolute value of a numeric value in the R programming language.

## Example Data

We use a simple numeric vector as example data. Note that some of the values of our vector are negative:

vec <- c(5, -3, 2, -5, -1) # Create example vector vec # Print example vector # 5 -3 2 -5 -1 |

vec <- c(5, -3, 2, -5, -1) # Create example vector vec # Print example vector # 5 -3 2 -5 -1

## Calculate Absolute Value in R (abs Function)

If we want to convert our numeric vector to strictly positive, we can apply the abs function as follows:

abs(vec) # Apply abs function # 5 3 2 5 1 |

abs(vec) # Apply abs function # 5 3 2 5 1

As you can see, all negative values were replaced by the corresponding positive value.
