resolve

idxs

If TRUE, the values are retrieved, otherwise not.

value

A non-negative number specifying how deep of
a recursion should be done.  If TRUE, an infintive recursion
is used.  If FALSE or zero, no recursion is performed.

recursive

Number of seconds to wait before checking
if futures have been resolved since last time.

sleep

If TRUE textual progress summary is outputted.
If a function, the it is called as <code>progress(done, total)</code>
every time a future is resolved.

progress

The environment is first scanned for futures and then the futures
are polled until all are resolved.  When a resolved future is
detected its value is retrieved (optionally).
This provides an efficient mechanism for waiting for a set of
futures to be resolved and in the meanwhile retrieving values
of already resolved futures.

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. 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, e.g.
    'f <- future({ mandelbrot(c(0.28,0), side=2) })' and 'v <- value(f)'.
    The 'resolve()' function can be used to check if a future is resolved or not.
    An infix assignment operator '%<=%' exists for creating futures whose values
    are accessible by the assigned variables (as promises), e.g.
    'v %<=% { mandelbrot(c(0.28,0), side=2) }'.
    This package implements synchronous "lazy" and "eager" futures, and asynchronous
    "multicore", "multisession" and ad hoc "cluster" futures.
    Globals variables and functions are automatically identified and exported.
    Required packages are attached in external R sessions whenever needed.
    All types of futures are designed to behave the same such that the exact
    same code work regardless of futures used or number of cores, background
    sessions or cluster nodes available.
    Additional types of futures are provided by other packages enhancing
    this package.

resolve: Wait until all existing futures in an environment are resolved
