NOTICE: plan(multiprocess) of future is deprecated

[HenrikBengtsson]

Hi. Please note that multiprocess is deprecated since future 1.20.0 (2020-11-03) and will soon be defunct:

https://github.com/rvalavi/blockCV/blob/3d43b5020078a56a1fab153613b7d270a458f289/R/spatialAutoRange.R#L162-L168

Also, please undo to the future plan to whatever was set before, which might not be sequential as assumed above. See section 'For package developers' in https://future.futureverse.org/reference/plan.html for how to do that, e.g.

oplan <- plan(new_set_of_strategies)
on.exit(plan(oplan), add = TRUE)

[HenrikBengtsson]

Just a friendly reminder that multiprocess will become defunct and eventually be removed. When that happens, your package will break and risk being archived on CRAN. My suggestion is to update to use multisession instead.

[rvalavi]

@HenrikBengtsson thank you so much for the notice. I'll fix it soon.

[HenrikBengtsson]

Friendly reminder; 'multiprocess' has been deprecated since 2020-10-30.

[rvalavi]

Thanks @HenrikBengtsson blockCV is now updated and this issue no longer exists. I'm closing this issue.

How is the CRAN submission going? My revdep checks gives:

══ Failed tests ════════════════════════════════════════════════════════════════

Sorry for the delay. The package is already submitted to CRAN. I'll let you know as soon as it's up.

[rvalavi]

Hi @HenrikBengtsson I just want to let you know that blockCV is finally on CRAN.

[HenrikBengtsson]

Thank you
