        # DeedleExtensions

This repository contains additional functions for handling Deedle frames. 

## Align

Especially the align function is a very handy tool, allowing easy and flexible multi key joining of two frames. 

For each frame, a function is given to the function which maps the keys of both frames to shared keys. The two frames are then joined in a way, that all combinations of rows mapping to the same shared key are created.

Let's say we have the two frames

#### frame1


                 Hometown   

Frank   Team1 -> Frankfurt  

Barbara Team1 -> Stralsund  

Alice   Team2 -> Wonderland 

Bruce   Team2 -> Cranberra  



#### frame2


         Room 

Team1 -> 28   

Team2 -> 42



We can join them over the shared teamName:

```F#

Frame.align snd id frame1 frame2

|> Frame.mapRowKeys (fun (team,(name,_),_) -> name,team)

```


                 Hometown   Room 

Frank   Team1 -> Frankfurt  28   

Barbara Team1 -> Stralsund  28   

Alice   Team2 -> Wonderland 42   

Bruce   Team2 -> Cranberra  42
