I'm not quite sure what "source the fonction" means.
The wmtsa package is available from the archive as a
compressed archive wmtsa_2.0-3.tar.gz.
% tar xf wmtsa_2.0-3.tar.gz
creates a directory wmtsa/ with subdirectories
wmtsa/man and wmtsa/R plus some other files.
The documentation is in wmtsa/man/*.md
The source code is in wmtsa/R/*.R
You look at either using whatever text editor you feel like.
Looking at wav_xform.R I see hundreds of lines of code
that only a mother could love, with a good table of contents
but no really informative comments anywhere.
I am reminded, as too often, that there are people who develop packages for
R, and there are software engineers, but there are precious few software
engineers developing packages for R.
As it happens, I *am* a software engineer (amongst other things),
and I do have a tolerably good knowledge of base R, and a high tolerance
for looking things up in the documentation. But I would have to be paid
quite a large sum of money before I would spend any time on this
code-base. There are other currently maintained packages that might be
able to do the job, so it would be a waste of my time.
My advice is
DON'T spend any time looking at this code.
An R beginning WON'T understand it.
DO ask your supervisor help you to select an alternative,
and if you can't figure that out between you,
ASK a more informative question.
