Execute/Share R and Python code

Step 1: Load R (exp. Google Colab cell)

%reload_ext rpy2.ipython

Step 2: Run R (exp. Google Colab cell)

%%R
# r imports …
library(ggplot2)

Step 3: Import data from R into Python (exp. Google Colab cell)

%R -o df1 -o df2

Step 4: Import data from Python into R (exp. Google Colab cell)

%R -i df3 -i df4
