Package

r-progressr

Description

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() or
progress::progress_bar(), in a graphical user interface using
utils::winProgressBar(), tcltk::tkProgressBar() or
shiny::withProgress(), via the speakers using beep::beepr(), 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.
