Hmm, if I try it (on my Linux desktop), I get

PhantomJS not found. You can install it with webshot::install_phantomjs(). If
it is installed, please make sure the phantomjs executable can be found via the
PATH variable.
NULL
So, it is clear this relies on extra javascript based software
being available on your computer, *and* having that correctly in
your PATH.
On my linux system, I then did
webshot::install_phantomjs()
and that downloaded things and installed a 67 Megabyte
executable in my PATH ... which then subsequently worked.
On that Linux system it did *not* work, try
system("which phantomjs")
and you should see that it gets a version of 'phantomjs' on your
computer, i.e., the one that webshot() will then try to use and
somehow fails.
I'd recommend you run webshot::install_phantomjs()
which then should install a "better" version of the 'phantomjs'
executable that then *should* work ..
Let us know if this helped (or why not).
