[R-pkg-devel] could not find function "%dopar%"

[Mohammad Ali Nilforooshan]

Problem solved!
`%dopar%` <- foreach::`%dopar%`


One of my functions does parallel processing with "doParallel" and
> "foreach". "foreach" is a dependency to "doParallel". My R package keeps
> failing, because %dopar% is not recognized as a function. I tried
> %foreach::dopar%, %parallel::dopar% , %doParallel::dopar%, and
> %iterators::dopar%. It didn't help!
