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 Sources tree that you would like to compute the case-level shares.
- Hover over any variable in your Data Sources tree > Plus (+) > Numeric Transformations > Log. 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 Data > Show Advanced Options > R Code > Edit Code, similar to below:
