EagerFuture

EagerFuture-class

An R <a href="/link/expression?package=future&version=0.8.0&to=base" rd-options="base" data-mini-rdoc="base::expression">expression</a>.

expr

The <a href="/link/environment?package=future&version=0.8.0" rd-options="" data-mini-rdoc="future::environment">environment</a> in which the evaluation
is done (or inherits from if <code>local</code> is TRUE).

envir

If TRUE, argument <code>expr</code> is
<code><a href="/link/substitute?package=future&version=0.8.0&to=base" rd-options="base" data-mini-rdoc="base::substitute">substitute</a>()</code>:ed, otherwise not.

substitute

If TRUE, the expression is evaluated such that
all assignments are done to local temporary environment, otherwise
the assignments are done in the calling environment.

local

An eager future is a future whose value will be resolved immediately

internal

A Future API for R is provided.  In programming, a future is an abstraction for a value that may be available at some point in the future.  The state of a future can either be unresolved or resolved.  As soon as it is resolved, the value is available.  Futures are useful constructs in for instance concurrent evaluation, e.g. multicore parallel processing and distributed processing on compute clusters.  The purpose of this package is to provide a lightweight interface for using futures in R.  Functions 'future()' and 'value()' exist for creating futures and requesting their values.  An infix assignment operator '%<=%' exists for creating futures whose values are accessible by the assigned variables (as promises).  This package implements the synchronous "lazy" and "eager" futures, and the asynchronous "multicore" future (not on Windows).  Additional types of futures are provided by other packages enhancing this package.
