This opened QuickTime Player and loaded Temp_Sound.wav. However, I
had to click on the play button to hear it.
As I mentioned before you can preset autoplay in QuickTime's
preferences and you can use the default 'play(s, stay=TRUE)'. There is
no need for myplay if you set stay to TRUE.
(2) Using the terminal-callable 'play' program.
I downloaded it from http://www.hieper.nl/html/play.html and
installed it and then checked its availability:
% which play
/usr/local/bin/play
> setWavPlayer('play')
[1] "WAV file player 'play' linked successfully."
Yes. 'play' can be invoked without stay=TRUE.
BTW with Audacity it works as well if stay=TRUE.
I rewrote the R code for findWavPlayer(), play.default(), and
play.Sample() to interact with Mac better.
Furthermore if options()$wavplayer is not a 'open -a' command the
chosen shell command runs in the background, thus you can with R
further without waiting for e.g. 'play'. This behavior led me to
introduce a new MacOSX function called 'stopPlay()' which kills the
shell process (if not 'open -a'). Additionally I changed these scripts
to use only one temp file. To work with it with QuickTime I also
included an Applescript to control QuickTime.
I will post my changes to Matthias Heymann who is the maintainer of
that package.
Cheers,
