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.

## 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)## End(Not run)
