A callr future is a future whose value will be resolved via callr
CallrFuture( expr = NULL, envir = parent.frame(), substitute = TRUE, globals = TRUE, packages = NULL, label = NULL, workers = NULL, supervise = FALSE, ... )
The R expression to be evaluated.
The environment in which global environment should be located.
expr should be
(optional) a logical, a character vector, a named list, or
a globals::Globals object. If
TRUE, globals are identified by code
inspection based on
tweak searching from environment
FALSE, no globals are used. If a character vector, then
globals are identified by lookup based their names
envir. If a named list or a Globals object, the
globals are used as is.
(optional) Label of the future.
(optional) The maximum number of workers the callr backend may use at any time.
(optional) Argument passed to
