count.fields() More generally, you might be interested in our approach to integrating data collection on the Web, using JavaScript, with R. See http://promberger.info/ (which says "private" but Google finds it pretty fast) http://finzi.psych.upenn.edu/~baron/ex/template.htm http://finzi.psych.upenn.edu/~baron/ex/template.html http://finzi.psych.upenn.edu/~baron/R/template.R http://finzi.psych.upenn.edu/~baron/R/TRIM.R The last makes a nice data file out of the JavaScript output (which is designed more to be readable at the moment than to be useful). It uses count.fields as a check. None of this stuff is ready for prime time. In my case, there is a 14-year history, with various baggage left over from earlier travels.
