Tools to run system processes in the background.
    It can check if a background process is running; wait on a background
    process to finish; get the exit status of finished processes; kill
    background processes. It can read the standard output and error of
    the processes, using non-blocking connections. 'processx' can poll
    a process for standard output or error, with a timeout. It can also
    poll several processes at once.

Adding Progress Bar to '*apply' Functions

Peter Solymos [aut, cre], Zygmunt Zawadzki [aut]

A lightweight package that adds
  progress bar to vectorized R functions
  ('*apply'). The implementation can easily be added
  to functions where showing the progress is
  useful (e.g. bootstrap). The type and style of the
  progress bar (with percentages or remaining time)
  can be set through options.
  Supports several parallel processing backends.

ANSI Control Sequence Aware String Functions

Counterparts to R string manipulation functions that account for
   the effects of ANSI text formatting control sequences.
