* For parallel processing, progress conditions can be relayed back to the parent process via back channels in a "near-live" fashion, or at the very end when the parallel task is completed. Technically, progress conditions inherit from 'immediateCondition', which is a special class indicating th...
conditions are a much better fit for progress tracking than callbacks. It would be even better if 'parallel' clusters could "officially" handle immediateConditions and re-signal them in the main R session. Since R-4.4 exports (but not yet documents) sendData, recvData and recvOneData generics ...
