Add a particular version of R to a docker container

Question

I am trying to install R in an Ubuntu docker image. I am able to successfully do so using this line:

RUN apt-get update && apt-get install -y r-base

but it is installing r 3.2.3. I need a newer version (3.5.2). Does anyone know how to specify which version to download?

Answer 1

Sure thing:

FROM ubuntu:18.10

ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update && apt-get -y install --no-install-recommends --no-install-suggests \
        ca-certificates software-properties-common gnupg2 gnupg1 \
      && apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 \
      && add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/' \
      && apt-get install r-base
