This indeed solves the first error - thank you for that! And now I am left with the other two. I am not sure if these are related to installation of AFNI and version of R? When I installed AFNI, I already had two versions of R on my workstation, one that I use regularly (R 4.0.3 in /usr/bin/R) and another one (R 3.6.3 in /opt/R/3.6.3/bin/R). I assumed AFNI was using the R in my path (which R=/usr/bin/R), but when I run the command lines to install R (i.e.sudo tcsh @add_rcran_ubuntu_18.04.tcsh), I get the following message:
+* Warning! Existing R version detected:
R version 3.6.3 (2020-02-29)
---------------------------------------------------------------
** If you still want to carry on with this installation,
you MUST use the following option with this command:
-overwrite
If you have any questions, please ask on the AFNI Message
Board.

I would rather not overwrite my current version of R (4.0.3) with an earlier version, so I have not yet tried this option. I don't know if it will be necessary for AFNI installation, and if this has anything to do with the error message that I am getting? (or if it is much simpler than that??) Thanks in advance for your help!
