Log Transformation of Data Frame in R (Example)
Table of contents:
You’re here for the answer, so let’s get straight to the example…
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.
