mac.expression: Expression Generator

Description

Help functions to easily generate commonly used expressions.

Usage

mac.expression(country)

Arguments

country

Country code as defined for expressions.

Value

• mac.expression returns a character string corresponding to the formula {$(17.5*R_c(15-19) + 22.5*R_c(20=24) + ... + 47.5*R_c(45-49))/100$} where $R_c(x)$ denotes the country-specific percent age-specific fertility for the age group $x$.

Details

mac.expression generates an expression for the mean age of childbearing of the given country. Note that pop.predict has to be run with keep.vital.events=TRUE for this to work.

Examples

# Run pop.predict with storing vital events
sim.dir <- tempfile()
pred <- pop.predict(countries=c("Germany", "France"), nr.traj=3, 
           keep.vital.events=TRUE, output.dir=sim.dir)
# plot the mean age of childbearing 
pop.trajectories.plot(pred, expression=mac.expression("FR"))
unlink(sim.dir, recursive=TRUE)
