Aggregate the age distribution matrix

Description

Function to aggregate the age distribution according to user-defined age groups.

Usage

aggregate_age_distribution(x, lookup_table)

Arguments

x	data.frame; an age distribution matrix. See age_distribution.
lookup_table	data.frame; a user-defined dataframe which maps the sixteen 5-year age bands to a new set of age bands.

Value

An object of class data.frame that contains the aggregated age distribution.

Examples

# Import the age distribution for Greece in 2020:
age_distr <- age_distribution(country = "Greece", year = 2020)

# Lookup table:
lookup_table <- data.frame(Initial = age_distr$AgeGrp,
                           Mapping = c(rep("0-39",  8),
                                       rep("40-64", 5),
                                       rep("65+"  , 3)))

# Aggregate the age distribution table:
aggr_age <- aggregate_age_distribution(age_distr, lookup_table)

# Plot the aggregated age distribution matrix:
plot_age_distribution(aggr_age)
