Hello my R friends, How can we call a music file from our laptop (for example from desktop) and play it in R? Could you please give me an explicit example by writing commands in R. Is it necessary for our music file to be in a specific format? If yes, which format it has to be? Thank you in advance [[alternative HTML version deleted]]
Google search "playing music with r" for example: https://stackoverflow.com/questions/31782580/how-can-i-play-birthday-music-using-r It can be a starting point Yousri On Tue, Jul 21, 2020 at 2:02 PM Vahid Borji <vahid.borji65 at gmail.com> wrote:> > Hello my R friends, > > How can we call a music file from our laptop (for example from desktop) and > play it in R?

Hi Vahid,
The following command:
system("mplayer /home/jim/songs/bimbo_soul.mp3",
wait=FALSE,ignore.stdout=TRUE)
works fine for me. Of course you'll have to specify a music player and
music file that you have...

It must be attached by the following line: setWavPlayer("/Library/Frameworks/R.framework/Versions/3.6/Resources/bin/play") # path depends on your R version etc. Then, a simple script like the following will do: inname = file.choose() ywave=readWave(inname) ster=ywave at stereo srate=ywave at samp.rate play(ywave) Hoping this helps, I remain With best regards, Franklin Bretschneider Dept of Biology Utrecht University f.bretschneider at uu.nl

Thie "system" command in R takes the first argument and passes that to the shell in which R is running. 1) I run R in the bash shell under Fedora Linux version 30 2) I have installed "mplayer" as an audio/visual player that can be called from the bash shell 3) The command I pass says "Start the mplayer program using the first argument as the file to process. One method is to find the easiest way to play an audio/visual file on your system and then call it from R using "system". Other ways using R packages have been suggested by other respondents.

Dear Vahid, Re:> I have a question regarding the following code: > setWavPlayer("/Library/Frameworks/R.framework/Versions/3.6/Resources/bin/play") # path depends on your R version etc. > > How can I find the corresponding path on my laptop?This line ... setWavPlayer("/Library/Frameworks/R.framework/Versions/3.6/Resources/bin/play") ... is the path on my MacBook Air running Mac OS Mojave. The structure of R on similar computers and OS versions will be the same, but I don't know if you use Windows or Linux. Maybe an R-user working with Windows or Linux can help.

The R command system.file() tells you where the currently running version of R is located on your machine and your operating system. On the Macintosh it shows> system.file()[1] "/Library/Frameworks/R.framework/Resources/library/base" You don't need to worry about the R version number, as R knows where it is and gives you the location of the currently running version. You can now open a system directory file (Finder on Mac, WindowsExplorer on Windows, etc) and navigate up and down to what you are looking for. Or, within R, you can navigate with .. and more directory statements, thus the example from the original email setWavPlayer("/Library/Frameworks/R.framework/Versions/3.6/Resources/bin/play") # path depends on your R version etc. would be written tmp <- system.file("../../bin/play") and the result is the correct location (if it is there). You will get an empty string if it is not ther, but this will get you started on where to look. then you write setWavPlayer(tmp) # path depends on your R version etc. On Thu, Jul 23, 2020 at 7:21 AM bretschr <bretschr at xs4all.nl> wrote:> > Dear Vahid, > > > Re: > > > I have a question regarding the following code: > > setWavPlayer("/Library/Frameworks/R.framework/Versions/3.6/Resources/bin/play") # path depends on your R version etc. > > > > How can I find the corresponding path on my laptop? > > > This line ... > > setWavPlayer("/Library/Frameworks/R.framework/Versions/3.6/Resources/bin/play") > > ... is the path on my MacBook Air running Mac OS Mojave. > The structure of R on similar computers and OS versions will be the same, but I don't know if you use Windows or Linux. > Maybe an R-user working with Windows or Linux can help. > Success, > > Franklin > ---- > > > > Franklin Bretschneider > Dept of Biology > Utrecht University > f.bretschneider at uu.nl > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
