if you want to use my approach above more widely you could name the code block say #+source:less-precision, then add :exports none to each of your existing code blocks that output over-precise data, and for each such block add a call of the following form #+call: less-precision(tab=overly-precise-R-block) :exports results which should work, but would litter your file with these call lines. I guess this is an instance where a post-processing function specified at the file/subtree level could potentially be useful.
