[datatable-help] Have monthly data, need log of the difference. How?

2018-01-30 Thread ellie
So I have monthly data in an excel file, but what I need to make my calculations in the natural log of the difference. Is there a built in function in R that will let me transform my data this way, or do I need to do it in excel before importing the data to R? Thanks! -- Sent from:

You can probably do it in R. Can you show an example of what you data looks like and then the type of transformation that you would like to do. Jim Holtman Data Munger Guru What is the problem that you are trying to solve? Tell me what you want to do, not how you want to do it. On Tue, Jan
