Please accept my apologies for attempting to be cute and I also apologize to Mr Bebber for reading his request far too quickly. I was trying to use (C)RAN (T)ask (V)iews as a verb.

I don't think it warrants being enshrined. I might also  have written:  require(sos); findFn("metric spherical latitude longitude")  might produce. In this instance that approach found the ramps::corRSpher function, which has a "haversine" metric, much  more quickly than did my subsequent efforts with RSeek, which I conducted after I realized that Bebber had already made a good faith effort at identifying resources.
