...or each ordered pair of a data frame (D1) containing longitudes and latitudes and unique point IDs, calculate the distance to every point in another data frame (D2) also containing longitudes, latitudes and point IDs, and return to a new variable in D1 the point ID of the nearest element of D2. Dramatis personae (mostly self-explanatory): D1$long D1$lat D1$point.id neighbor.id (to be created; for each ordered pair in D1 the point ID of the nearest ordered pair in D2) D2$long D2$lat D2$point.id dist.geo (to be created) I've been attempting this with nested for() loops that step thro...

...viour ------------------ That hist() should never crash when given valid numerical data. Specifically, that it should be robust even to those rare datasets where (through floating point inaccuracy) the inter-quartile range is tens of orders of magnitude smaller than the range.
