# R images 
# see for more image:
# https://hub.docker.com/u/rocker/
#

# Version-stable build of R, rstudio, and R packages ~2.48GB
# FROM rocker/tidyverse:latest

#
# In this case I will use the r-base image by adding some debian packages 
# necessary for the correct build of the image.
# So, I will obtain an image of ~1.2GB.
# Better ad-hoc solutions can be found to reduce the image size.
#
# Base Version ~824MB
