My first idea was to get R version 4 on my rstudio beside anaconda

My ADD brain then fought getting the newest version of R in my base environment

I have before created new conda environments with different versions of R without a problem

Now I start R in my Ubuntu 18.04.5 and get:

R version 3.5.1

I download the newest version of R (should be 4.0.5) with conda install -c conda-forge r-base

I restart the computer but I am stuck in R version 3.5.1

I do conda update -n base conda and nothing changes

conda config --show-sources

==> /home/notandi/anaconda3/.condarc <==
channels:
  - conda-forge
  - bioconda
  - defaults

==> /home/notandi/.condarc <==
channels:
  - bioconda
  - defaults

The best solution for me is to update the place where Anaconda is looking for the packages. To do that:

  1. Open Anaconda
  2. Go to Environments and select your desired environment
  3. Lets add a new channel to look for updated packages: button Channels --> click Add --> type conda-forge --> enter --> click Update Channels
  4. Lets wait until Anaconda update packages list and look for the R package (now it should show you the last version) and either update it or installed it from crash.
