- expr
The R expression to be evaluated
- envir
The environment in which global environment
should be located.
- substitute
Controls whether expr
should be
substitute()
:d or not.
- globals
(optional) a logical, a character vector, a named list, or a
Globals object. If TRUE, globals are identified by code
inspection based on expr
and tweak
searching from environment
envir
. If FALSE, no globals are used. If a character vector, then
globals are identified by lookup based their names globals
searching
from environment envir
. If a named list or a Globals object, the
globals are used as is.
- label
(optional) Label of the future (where applicable, becomes the
job name for most job schedulers).
- resources
(optional) A named list passed to the batchtools
template (available as variable resources
). See Section 'Resources'
in batchtools::submitJobs()
more details.
- workers
(optional) The maximum number of workers the batchtools
backend may use at any time. Interactive and "local" backends can only
process one future at the time (workers = 1L
), whereas HPC backends,
where futures are resolved via separate jobs on a scheduler, can have
multiple workers. In the latter, the default is workers = NULL
, which
will resolve to
getOption("future.batchtools.workers")
.
If neither are specified, then the default is 100
.
- conf.file
(character) A batchtools configuration file as for
instance returned by batchtools::findConfFile()
.
- cluster.functions
A
ClusterFunctions object.
- registry
(optional) A named list of settings to control the setup
of the batchtools registry.
- ...
Additional arguments passed to BatchtoolsFuture()
