sh>geany -g "/usr/local/build/R.tags" ... atticist/R/latticist.R" (5603) returned '1' Opening the file in Geany will correctly identify two tags (Functions, in Symbols). However, even if geany -g worked on .R files, the approach would be difficult to apply in practice. It requires the user to specify .R files, and given the structure of R packages this could be a quickly become tedious. It would have been much easier if Geany accepted a path in which it could recursively scan (and parse) R files. The rtags() function can do that, so it might make sense to find a conversion route for etags files. > No, thats why I said you need to convert it yourself, sorry.

But here's [1] what I found as close as possible to a spec. Could you please take a look and let us know whether there's some resemblance with the Geany format, for a potential conversion route?
