Installing R packages from subversion

I'm trying to install an R package from subversion. I thought I've installed subversion on my computer but it's still not working. Any ideas?

I'm on Windows and installed both of these:

remotes::install_svn(
  url="https://r-forge.r-project.org/scm/viewvc.php/?root=r-survey")
#> Error: Failed to install 'unknown package' from SVN:
#>   SVN does not seem to be installed on your system.

If svn on the PATH? I.e. can Sys.which("svn") find it? If not, then you'll probably need to put it on the PATH.
