The installation of R and R magic into Jupyter notebook is described here:

https://www.datacamp.com/community/blog/jupyter-notebook-r#gs.z0gxLNc

Or you can run it all in the docker and do not care about installation

https://github.com/jupyter/docker-stacks/tree/master/datascience-notebook

And even better, you can run it all in the cloud and do not care about anything, except your credit card bill (~$0.05 / hour you actually use it)

Can you explain what this piece of code is doing? (also is this part of R magic or is it just part of R). Thanks, I'm just wrapping my head around R magics.

df %>%
gather("Category", "X") %>%

@drwecki, the pipe operator %>% just pushes the first thing into the second, so this code is equivalent to:

gather(df, "Category", "X")

And the gather function takes data from multiple columns and collapses them into key-value pairs
