Answer 1

rtags() is the best to way to generate tags for R codes from what I see so far, since it will take all different ways of assignments in consideration, such as:

ok = c("<-", "=", "<<-", "assign",
       "setGeneric", "setGroupGeneric", "setMethod",
       "setClass", "setClassUnion")

An example of using rtags():

path <- "~/path/to/project"
rtags(path=path,
      pattern = "[.]*\\.[RrSs]$",
      keep.re = ".", # the value ('/R/') in the help page will only run through the codes in R/ folder.
      verbose = TRUE,
      ofile = file.path(path, 'TAGS'),
      append = FALSE,
      recursive = TRUE)
