Check if multisession is running in future R

Time：12-06

Is there a quick way to check if multiple processes were generated by future package on the current R?

In other words, to check whether plan(multisession) or similar was run in R?

CodePudding user response：

As it is said in the comments, you can check (in the main process) the class of the object (a function) returned by plan() with no arguments.

library(future)

is(plan(), "multisession")   # TRUE if plan(multisession) is set FALSE otherwise
is(plan(), "sequential")     # ...
...
