foreachDoparLocal
system option to TRUE.
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.
%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.
