Log Transformation of Data Frame in R (Example)

In this article, I’ll demonstrate how to apply a log transformation to all columns of a data frame in the R programming language.

You’re here for the answer, so let’s get straight to the example…

Example Data

As a first step, we have to create some data that we can use in the example code later on:

data <- data.frame(x1 = 1:5,    # Create example data frame
                   x2 = 11:15,
                   x3 = 10:6)
data                            # Print example data frame

Table 1 shows that our example data consists of five rows and three columns.

Example: Generate Log Transformation of All Data Frame Columns Using log() Function

This example explains how to perform a log transformation for all columns of a data frame.

For this task, we can apply the log function as shown below:

data_log <- log(data)           # Log transformation
data_log                        # Print log transformed data

As illustrated in Table 2, we have created a new data frame called data_log, which contains the log transformed values of our input data frame.
