determine the age range that minimizes the mean squared error

Description

Called by ggbcoverageFromYear() whenever exact.ages are not given. This automates what one typically does visually.

Usage

ggbgetAgesFit(codi, minA = 15, maxA = 75, minAges = 8,
  deaths.summed = FALSE)

Arguments

codi

a chunk of data (single sex, year, region, etc) with all columns required by ggb()

minA

the lowest age to be included in search

maxA
