Hi, Richard: Thanks for the question.
"Source the function" means the following.
1. Go to "https://cran.r-project.org/"; and download the most recent
version. To do that, I found "archived" under "Related Directories". I
clicked on that and then searched for "wmtsa". To the right of that, it
says it was "Last Modified" "2020-06-09 07:24". Note that "Last
Modified", because you can use that to find recent documentation, etc.,
from "archive.org" shortly prior to that date.
2. Click on "wmtsa". That takes you to "Index of
/src/contrib/Archive/wmtsa", which includes 11 different versions of the
source code for that package from "wmtsa_1.0-1.tar.gz 2007-09-23 21:54
139K" to "wmtsa_2.0-3.tar.gz 2017-12-06 12:14 151K" Click on the last
one to download it. This downloaded a file by that name to the
"Downloads" folder in my computer.
3. Create a directory for that file. I have a directory called "R"
on my computer. I just created a new directory called "wmtsa" within
that "R" directory. Then I moved that file into that directory and
unzip it by double clicking on it. As a result, I now have a directory
"~R/wmtsa/wmtsa".
4. To compile that package, I routinely in a Terminal in R (called
something else in Windows), I "cd" until I get to "~R/wmtsa". Then I
run "R CMD check "wmtsa_2.0-3.tar.gz". I just did that. It said,
"ERROR Packages required but not available: 'splus2R', 'ifultools'".
In R, I was able to download the first using
"install.packages('splus2R')". When I tried
"install.packages('ifultools')", I got a message, "package ‘ifultools’
is not available for this version of R".
5. However, the inner "wmtsa" directory contains, among other
things, directories called "man" and "R". The latter directory contains
files with names like "wav_boot.R", ..., "wav_xform.R". I'm assuming
you have documentation that tells you which function(s) you want to run.
Let's say you want to run "wavBestBasis". If you are lucky, there
will be a file with a name like "wavBestBasis.R". That doesn't work in
this case. So instead I did a cd into that ~R/wmtsa/wmtsa/R". Then I
did "grep 'wavBestBasis' *.R". I got the following:
wav_xform.R:## wavBestBasis
wav_xform.R:# wavBestBasis
wav_xform.R:"wavBestBasis" <- function(costs)
Let's say it says you want to start with a f
6. That says that "wavBestBasis" is in file "wav_xform.R". I opened
that file in RStudio (I use the free version) then clicked on the
"Source" button in the upper right.
7. Also, in the directory "~R/wmtsa/wmtsa/man" I found a file called
"wavBestBasis.Rd". I opened that in R. To learn how to read that, you
can type "help.start()", which will open a menu that includes, "Writing
R Extensions". Click that. That tells you how to write (and read) a
*.Rd file. That file "wavBestBasis.Rd" contains and "\examples"
section. The first line in that section is "W <-
wavDWPT(diff(atomclock), n.level=6)". I ran that, and got:
Error in diff(atomclock) : object 'atomclock' not found
I won't discuss how to find "atomclick". If you need that, you can
ask again.
Hope this helps.

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.

Spenser,
the idea to source the fonction makes sense but since tho OP is a very
new beginner perhaps you could point him towards code showing him how
to do this? I have never done this AFAIR, and while I suspect a few
minutes googling would show me how, it is likely to be more difficult
for a noobie.
