Brilliant! Ben, while interfacing C code to R is very well established.

I would not suggest that. Using system is just a "hack" in my opinion.
It is preferable to have a proper interface to R via .C  in a package framework.

Concerning license, It is the responsibility of user/developer to
consider that :)

thanks Ben - that sounds a lot more efficient

   I wouldn't bother to try to write a native R version.  Since  getting
R to talk to compiled C code, is pretty easy, if I wanted to integrate
it more closely into R I would take the C code and figure out how I
could integrate it into an R package as compiled code with a thin R
wrapper around it. Since the code "license" is "public domain", you
could even redistribute the package freely. But if it's just for
personal use, and you don't need it to be incredibly slick, using it
externally (via system()) seems perfectly sensible.

Re: [R] Is there a package to output midi files for sonification of data

[Greg Hooper]

thanks again Mehmet - the midicsv utility is in C (of which I am ignorant).
I will have a look at that to see if I can write a native R version. It
only has to do midi_in and midi_out, the rest can be left up to R. That
will take me ages, but I can just use the utility externally for the moment

Hi Greg, Yes you are right, It is for wav analysis but as Ben
suggests. Conversion
should not be difficult. Also I think it must be 'trivial' to
translate that Perl
script's (package) to R, if you are really after pure R solution.

It is interesting. Can you do some meaningful data exploration with
playitbyr or is it
pure fun?

> there to midi. PlayitbyR and into Csound might be something that suits your

If you are going to use external program to convert that maybe you can
use wav files after all, hence the tuneR.

Hi Greg, Yes you are right, It is for wav analysis but as Ben

should not be difficult. Also I think it must be 'trivial' to

script's (package) to R, if you are really after pure R solution.

Re: [R] Is there a package to output midi files for sonification of data

[Greg Hooper]

thanks Ben - hmm I think I will use a midi/csv utility
http://www.fourmilab.ch/webtools/midicsv/ and see how that goes. Another
option is http://playitbyr.org/index.html and output to Csound and from
there to midi. PlayitbyR and into Csound might be something that suits your
work, Csound being enormously powerful although a bit clunky to use -
although I haven't used it in about 10 years - maybe it has improved since
then, perhaps I'd better look  :)

thanks, Greg



>tuneR writes Wave (.WAV?) files as output; it can also write output

  Bottom line, I think you may have to use an external program to
convert Wave to midi, or something.  It wouldn't be too hard to
write ABC (http://abcnotation.org) output and run it through abc2midi ...
http://rpubs.com/bbolker/3237 is an example of some stuff I was
playing with recently along these lines.

  I don't see any midi input anywhere ... library("sos"); findFn("midi")
doesn't give a lot of hits ...

[R] Is there a package to output midi files for sonification of data

[Greg Hooper]

Hi, I have been using Matlab to produce midi files for sonfication and
algorithmic composition projects. I would like to transfer that work into R
(in which I am a total newbie) and have been looking for a package that can
read and write midi files. No success so far so does anyone know of one? I
have seen that I can output to csv and then use a utility to convert csv to
midi (and vice-versa). But native R would be better if possible.
thanks for any help, Greg
