[Question]REPL in docker or singularity images

[pirocv]

Hi. Thanks for a great plugin! I’m facing a problem when I’d like to use R in docker or singularity image as REPL. I tried let g:neoterm_repl_r=‘singularity exec ~/singularity_img/saige_0.43.2.sif R’ or let g:neoterm_repl_r=‘/path/to/singularity exec /path/to/singularity_img/saige_0.43.2.sif R’ in init.vim file. But they did not work.

The following command lauches R in singularity image and works fine. singularity exec ~/singularity_img/saige_0.43.2.sif R

I’m new to neoterm, so I’m not sure I’m asking a appropriate question. Do you have any suggestions? I'm using nvim 0.4.4. Many thanks in advance.
