I have a measurement of 8165.666 and an uncertainty of 338.9741 (the units of both are unimportant). I can easily round the uncertainty to two significant digits with signif(338.9741,2), which gives 340. Is there a function in R that will take 8165.666 and round it to be consistent with its uncertainty, i.e., 8170?
That's not consistent, you have 3 significant digits here, but 2 for the "uncertainty" (whatever that is) ...
