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	the highest age to be included in search (the lower bound thereof)
minAges	the minimum number of adjacent ages to be used in estimating
