Non-geographic companion to geo_estimate_up(). Use this when you already
have a vector of group assignments.
estimate_up(value, group)Numeric vector to aggregate. Defaults to 1.
Integer vector of length length(value) giving the destination
row for each value, often from geo_match().
numeric vector of length max(group) with values aggregated by group
