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

# NOT RUN {
sim.dir <- tempfile()
# Run pop.predict with storing vital events
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"), cex.main = 0.7)
unlink(sim.dir, recursive=TRUE)
# }
