beepr is an R package that contains one main function,
beep(), with one purpose: To make it easy to play notification sounds on whatever platform you are on. It is intended to be useful, for example, if you are running a long analysis in the background and want to know when it is ready.
A derivative function,
beep_on_error(), wraps an expression and will only beep if an error occurs when that expression is evaluated.
This package was previously called
pingr and included a
ping() function. It has been renamed in order to not be confused with the Unix tool ping. For the rationale behind
beepr see the original announcement: http://sumsar.net/blog/2014/01/announcing-pingr/
beepr is available on CRAN and can be installed from within R by running:
You can also grab the development version of
beepr directly from github:
If you are using Windows or OS X
beepr relies on the
audio package for sound playback and no external program is needed.
If you're on Linux
beepr relies on you having either the
paplay utility from the Pulse Audio system, the
aplay utility from the ALSA system or VLC media player installed and on the PATH. Chances are that you alread have one of these. If you are on Debian/Ubuntu you can otherwise get VLC by running the following in a terminal:
sudo apt-get install vlc
beep() plays a short sound which is useful if you want to get notified, for example, when a script has finished. As an added bonus there are a number of different sounds to choose from.
beep(sound = 1, expr = NULL)
sound character string or number specifying what sound to be played by either specifying one of the built in sounds or specifying the path to a wav file. The default is 1. Possible sounds are:
sound does not match any of the sounds above, or is a valid path, a random sound will be played.
expr An optional expression to be executed before the sound.
# Update all packages and "ping" when it's ready update.packages(ask=FALSE); beep() #Play a fanfare instead of a "ping". beep("fanfare") #or beep(3) # Play a random sound beep(0) # Play a sound if an error occurs beep_on_error(1 + "a", sound = "wilhelm")
paplayto play audio on Linux.
aplayis now tried first and VLC is used as the last resort.
