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,
  ...
)

Arguments

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::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.
workers: (optional) The maximum number of workers the callr backend may use at any time.
supervise: (optional) Argument passed to callr::r_bg().
...: Additional arguments passed to future::MultiprocessFuture().
