I have an R notebook in colab where I want to read a file which is saved in my google drive.
I only seem to find python code such as \"from google.colab import driv
It seems there is no mechanism as of now to mount google drive in colab notebook with R kernel. Although a workaround can be used to have google drive mounted normally as in pyhton kernel and use both python and r based on the needs. See this answer which explains how r and python can be run together.
# activate R magic
%load_ext rpy2.ipython
%%R
x <- 42
print(x)
