random.cat.apply: Generation of random age ranges

In mortAAR: Analysis of Archaeological Mortality Data

Generation of random age ranges

Description

Helper function that generates random age categories of absolute ages. It is mainly used together with the functions pop.sim.gomp and random.cat.apply. It will run until the number of categories are reached and there are no gaps in the sequence left.

Helper function that applies random age categories to "known" absolute ages. It is mainly used together with the functions pop.sim.gomp and random.cat.

Usage

random.cat(n_cat = 20, min_age = 15, max_cat_low = 60, max_age = 74)

random.cat.apply(x, age, age_ranges, from, to)

Arguments

n_cat	numeric. Number of categories, default: 20.
min_age	numeric. Minimum age, default: 15.
max_cat_low	numeric. Lower boundary of highest age categoriy, default: 60.
max_age	numeric. Maximum age, default: 74.
x	a data.frame with individual absolute ages.
age	the column containing the individual absolute ages.
age_ranges	a data.frame with age ranges.
from	numeric. Column name for the begin of an age range.
to	numeric. Column name for the end of an age range.

Value

One data.frame with the following items:

• from: Lower boundary of age category.

• to: Upper boundary of age category.

The original data.frame x with two additional columns:

• from: Lower boundary of age category.

• to: Upper boundary of age category.

Examples

sim_ranges <- random.cat()

# Simulate population and age ranges first
pop_sim <- pop.sim.gomp(n = 10000)
sim_ranges <- random.cat()

# apply random age categories to simulated ages
sim_appl <- random.cat.apply(pop_sim$result, age = "age",
age_ranges = sim_ranges, from = "from", to = "to")
