Arguments

expr

An R expression.

envir

The environment from where global objects should be identified.

substitute

If TRUE, argument expr is substitute():ed, otherwise not.

globals

(optional) a logical, a character vector, or a named list to control how globals are handled. For details, see section 'Globals used by future expressions' in the help for future().

packages

(optional) a character vector specifying packages to be attached in the R environment evaluating the future.

lazy

If FALSE (default), the future is resolved eagerly (starting immediately), otherwise not.

local

If TRUE, the expression is evaluated such that all assignments are done to local temporary environment, otherwise the assignments are done to the global environment of the R process evaluating the future.

gc

If TRUE, the garbage collector run (in the process that evaluated the future) only after the value of the future is collected. Exactly when the values are collected may depend on various factors such as number of free workers and whether earlySignal is TRUE (more frequently) or FALSE (less frequently). Some types of futures ignore this argument.

earlySignal

Specified whether conditions should be signaled as soon as possible or not.

label

An optional character string label attached to the future.

required_resources

resources, see scripts_post_containers

docker_image_name

the image for the container script.

docker_image_tag

the tag for the Docker image.

...

arguments to scripts_post_containers

future

CivisFuture object.

object

CivisFuture

Value

A CivisFuture inheriting from Future that evaluates expr on the given container.
