How to use R with Google Colaboratory?

问题

Google Colaboratory supports Python version 2.7 and 3.6

I see an example how to use Swift in Colab a while ago.

Today, I happened to run

!jupyter-kernelspec list

And found a new kernel: IRkernel

Available kernels:
  ir         /usr/local/share/jupyter/kernels/ir
  python2    /usr/local/share/jupyter/kernels/python2
  python3    /usr/local/share/jupyter/kernels/python3
  swift      /usr/local/share/jupyter/kernels/swift

Is it now possible to use R in Colab as well? No hassle in installing R kernel?

回答1:

Yes.

You can simply run the demo.ipynb from IRkernel Github.

Make changes and then save a copy to your Google Drive.

You can also see all 3 example notebooks here.

回答2:

In case you want to use Python and R together, you can use R magic for some cells.

# activate R magic
%load_ext rpy2.ipython

Then, whenever you want to use R, you begin the cell with %%R

%%R
x <- 42
print(x)
