Options used by the doFuture adapter

Below are all R options specific to the doFuture package. For options controlling futures in general, see the options for the future package.

WARNING: Note that the names and the default values of these options may change in future versions of the package. Please use with care until further notice.

Details

doFuture.foreach.export:

Specifies to what extent the .export argument of foreach() should be respected or if globals should be automatically identified.

If ".export", then the globals specified by the .export argument will be used "as is".

If ".export-and-automatic", then globals specified by .export as well as those automatically identified are used.

The ".export-and-automatic-with-warning" is the same as ".export-and-automatic", but produces a warning if .export lacks some of the globals that the automatic identification locates

• this is helpful feedback to developers using foreach().

(Default: ".export-and-automatic")

doFuture.debug:

If TRUE, extensive debug messages are generated. (Default: FALSE)

Environment variables that set R options

All of the above R doFfuture.* options can be set by corresponding environment variable R_FOFUTURE_* when the doFuture package is loaded. For example, if R_DOFUTURE_DEBUG=TRUE, then option doFuture.debug is set to TRUE (logical).
