The remark 'in PHP the switch statement is considered a looping structure for the purposes of continue' near the top of this page threw me off, so I experimented a little using the following code to figure out what the exact semantics of continue inside a switch is:Īnd observed the different results.

Here's an example that does that: library(foreach)

Use a backend that supports calling combine on-the-fly, like doMPI or doRedis.

You could implement that by writing a custom combine function, and arranging for foreach to call it as soon as each result is returned. It sounds like you want an impatient version of the 'stop' error handling. Loaded via a namespace (and not attached): stats graphics grDevices utils datasets methods base Note that in reality I want to run all of the elements of this loop (here 10) in parallel.

Here is a simplified, reproducible version of what I am attempting (shown here in serial with %do%, but I have the same problem when using doRNG and %dopar%). Note that I cannot use a simple for loop, because ultimately I want to parallelize this using the doRNG package. In particular, break() does not work and stop() only stops the current calculation, not the whole foreach loop. However, I have not found a way to achieve this, and from the documentation and various forums I have found no indication that this is possible. I would like the ability to stop the entire set of calculations in the event that one of them produces an error. I am using the R package foreach() with %dopar% to do long (~days) calculations in parallel.
