This could be a bug in the RiverSmooth function. It could be trying to
access a variable called "active" without defining it first. Where did
you get this function? It's not anywhere on CRAN, as far as I can tell:

As you can see in my quoted part and in the archive at
<https://stat.ethz.ch/pipermail/r-help/2022-March/474078.html>, the
code in your message as we see it is somehow in ALL CAPS. When you
compose your messages to this list in HTML, your mailer tries to
automatically create a plain text version, typically mangling it in
process, while the list strips the HTML part for security reasons.
Please compose your messages in plain text.
