README
# M
This repo contains custom functions in the language M, which can be used in Power BI, Power Query (or Get & Transform) in Excel or in Analysis Services (version 2017 upwards).
This video describes how to use them: https://www.youtube.com/watch?v=6TQN6KPG74Q
There are currently 2 libraries:
+ Library: Main library who holds pure M-functions
+ LibraryR: Holds M-functions that contain R-code. So you need to have R installed for them to run. But once installed and configured, you can use these functions just like the other M-functions. Further details check out here: [Using R in the Query Editor]( https://docs.microsoft.com/en-us/power-bi/desktop-r-in-query-editor)
