%description
The 'future' package provides a unifying parallelization framework for R
that supports many parallel and distributed backends. The 'foreach'
package provides a powerful API for iterating over an R expression in
parallel. The 'doFuture' package brings the best of the two together.
There are two alternative ways to use this package. The recommended
approach is to use 'y <- foreach(...) %%dofuture%% { ... }', which does not
require using 'registerDoFuture()' and has many advantages over '%%dopar%%'.
The alternative is the traditional 'foreach' approach by registering the
'foreach' adapter 'registerDoFuture()' and so that 'y <- foreach(...)
%%dopar%% { ... }' runs in parallelizes with the 'future' framework.
