I have been using R (mostly through RStudio) for many years now and I am by no means a software developer, rather a user (analyzing large quantities of biomedical data).
How does one begin to troubleshoot issues with parallelization through RStudio?
Most of the time I am interactively building analysis pipelines. For parallel computation I use either future or parallel packages. Future is not supported from within RStudio, this is clearly stated when one tries. In the past, parallel package used to work (on-off, sometimes it would, sometimes it wouldn't) but recently I cannot get a simple mclapply to run from RStudio. Running the same code from R session launched from Terminal works just fine (in parallel, but also future). So, I am guessing either my system is somehow different now (currently on Ubuntu 20.04) or RStudio is different (1.3.1073).
Can someone point me in the right direction, to start troubleshooting? Right now I am switching between Terminal and RStudio and that is very frustrating and cumbersome.
Appreciate any input I can get on this.
