Custom directory for caching about treetools HOT 3 CLOSED

Thanks for the question. I suspect the answer will be to modify the cache settings of the underlying R.cache package. I'll look into whether there's a straightforward way to do so!

I found an approach that works. More background on the issue: when I run my analysis with Singularity I have to use --no-home option to prevent Singularity from looking for R packages in my host system (would defeat the purpose of a container) but then R.cache cannot create and populate the ~/.cache/R/R.cache directory. A potential solution is to tell Singularity not to use my home in general BUT bind my working directory as my home using the --no-home --bind <workdir>:$HOME option. This way if any tools want to create anything in my home they will create it in the working directory instead.

Alternatively, R.cache::setCacheRootPath() could be used to set a cache path for R.cache but I couldn't get it to work properly; it seems when I load R.cache it looks for the non-existing path and then fails with an error before I get a change to set another path.

Since this issue only comes up when using containers and can be solved from the container side, I think it can be closed.

Thanks for following up on this, and glad to hear that you were able to find a solution.
