[ESS] Run roxygen examples: how now?

Can you try with the latest ESS version (i.e. get it from MELPA rather
than use 18.10)?[1]

If that still doesn't work, you might have to do a bit of
troubleshooting to find the issue since it's working for me. Here's a
list of things to look at:

- make sure ess-roxy-mode is on
- make sure ess-roxy-remove-roxy-re is in ess-presend-filter-functions
- make sure ess-roxy-re looks like it matches roxy comments

I guess that's possible, but it seems pretty unlikely.
