make_stationary_popn: Calculate an implied stationary population
In johnrbryant/agesim: Simulate Age Structures in Small Populations

Description Usage Arguments Details Value See Also Examples

Calculation the stationary (ie zero growth rate) population implied by a given combination of total population size, life table Lx, and sex ratio.

make_stationary_popn(
  popn_size,
  Lx,
  sex_ratio,
  time_start = NULL,
  time_end = NULL
)

`popn_size`	The total population size.
`Lx`	A `Counts` array with the life table Lx values.
`sex_ratio`	The number of male births per 100 female births.
`time_start`	First time point. Optional.
`time_end`	Last time point. Optional.

Lx must be a Counts array with two dimensions. The dimensions must have dimtype "age" and "sex". The "age" dimension must have dimscale "Intervals".

If time_start and time_end arguments are supplied, a time dimension is added to the result.

A Counts object, with the same dimensions as Lx.

Lx <- dembase::Counts(Lx_west[ , , "10"])
make_stationary_popn(popn_size = 100,
                     Lx = Lx,
                     sex_ratio = 105)
make_stationary_popn(popn_size = 100,
                     Lx = Lx,
                     sex_ratio = 105,
                     time_start = 2000,
                     time_end = 2010)
