To answer my own question, the check is
>> browser(expr = {

>> })
I think that there are NAs in xseg, which I don't see a check for. In
particular, a few lines above, there's
>> md = median( xseg, na.rm = TRUE);
>> if (robust) sdd = mad(xseg,na.rm = TRUE)
>> else sdd = sd(xseg,na.rm = TRUE)
...which seems to suggest they are expected to happen there.

Not sure which advice to give regarding the choice of file hosting
service. On the one hand, SourceForge lets you upload a whole directory
of files in arbitrary formats, but isn't very convenient do download
more than one file from. On the other hand, "pastebin" services like
http://paste.debian.net/ or http://paste.org.ru/ let us browse the code
right away, without having to look at the "Your download will start
shortly..." screen, but don't host *.RData or more than one file per
link. I guess that some other code hosting service like
SourceHut/GitHub/GitLab/Gitea/... could fulfil both criteria.

I would take one step back, and suggest that if any project has as many 
scripts as this one, it should be put in an R package.  You can 
distribute that by building it into a tar.gz file and putting that 
single file in a place where people can download it.  Github and R-forge 
work well for packages, and I assume other hosting services do too, 
though I haven't used many.

People seem to be unreasonably reluctant to put their code into packages.
