progressr: An Inclusive, Unifying API for Progress Updates
A minimal, unifying API for scripts and packages to report progress updates
from anywhere including when using parallel processing. The package is
designed such that the developer can to focus on what progress should be
reported on without having to worry about how to present it. The end user
has full control of how, where, and when to render these progress updates,
e.g. in the terminal using utils::txtProgressBar(),
cli::cli_progress_bar(), in a graphical user interface using
utils::winProgressBar(), tcltk::tkProgressBar() or shiny::withProgress(),
via the speakers using beepr::beep(), or on a file system via the size of a
file. Anyone can add additional, customized, progression handlers. The
'progressr' package uses R's condition framework for signaling progress
updated. Because of this, progress can be reported from almost anywhere in
R, e.g. from classical for and while loops, from map-reduce API:s like the
lapply() family of functions, 'purrr', 'plyr', and 'foreach'. It will also
work with parallel processing via the 'future' framework, e.g.
future.apply::future_lapply(), furrr::future_map(), and 'foreach' with
'doFuture'. The package is compatible with Shiny applications.
