...g functions with arguments and returning value). * 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 that such conditions are allowed to be relayed immediately and out of order. It is possible to use the existing PSOCK socket connections to send such 'immediateCondition':s. * No assumption is made on progress updates arriving in a certain order. T...

Hello R-devel, A function to be run inside lapply() or one of its friends is trivial to augment with side effects to show a progress bar. When the code is intended to be run on a 'parallel' cluster, it generally cannot rely on its own side effects to report progress. I've found three approaches to progress bars for parallel processes on CRAN: - Importing 'snow' (not
