**Log transformation** is a data **transformation** method that replaces each variable x with a **log**(x). This article describes how to apply the log transformation to numeric variable sets, for example:

## Requirements

- A Displayr document containing numeric data.

## Method

- Select the numeric variable in the
**Data Sets**tree that you would like to compute the case-level shares. - Either hover over any variable in your
**Data Sets**tree**> Plus (+) > Insert Variable(s) > Ready-Made New Variable(s) > Log Transform Variable(s)****Anything > Data > Variables > New > Ready-Made New Variable(s) >****Log Transform Variable(s)**. This will create a new numeric variable that is the log(x) using R. - The code that has been used can be found in the
**object inspector**under**Properties > R CODE**, similar to below:
