In RevolutionAnalytics/foreach: Provides Foreach Looping Construct

1.5.2 (2022-01-10)

• Maintainer change (Folashade Daniel; [e-mail])

1.5.1 (2020-10-12)

• Maintainer change (Michelle Wallig; [e-mail])

1.5.0 (2020-03-29)

• Changed the default value for the foreachDoparLocal system option to TRUE.

1.4.8 (2020-02-04)

• Added preliminary support for evaluating `%dopar%` expressions in a local environment, when a sequential backend is used. This addresses a long-standing inconsistency in the behaviour of `%dopar%` with parallel and sequential backends, where the latter would evaluate the loop body in the global environment by default. The behaviour of `%dopar%` can be controlled by setting `options(foreachDoparLocal=TRUE|FALSE)` or equivalently via the system environment variable `R_FOREACH_DOPAR_LOCAL=TRUE|FALSE` with the R option taking its value from the environment variable. If both are set, the former overrides the latter. The current default value is FALSE, which retains the pre-existing behaviour. It is intended that over time this will be changed to TRUE. A side-effect of this change is that the behaviour of `%do%` and `%dopar%` will (eventually) be different for a sequential backend. See https://github.com/RevolutionAnalytics/foreach/issues/3 for more discussion on this issue.

• Updated tooling used for development. None of these changes should have any effect on package behaviour.
