lifeTable_calculate_all: Calculate All Parameters of One Life Table

In insectecol: Insect Ecology Data Analysis Toolkit

Calculate All Parameters of One Life Table

Description

Convenience wrapper that computes all life table parameters of one data set in a single call: cohort size, mean fecundity, the age-stage survival rates, the age-specific rates and the derived population parameters (R0, r, lambda, T).

Usage

lifeTable_calculate_all(lt, fecundity = TRUE)

Arguments

lt	A life_table object returned by lifeTable_read.
fecundity	Logical; whether to compute the reproduction-related parameters (F, F_xj, m_x, R0, r, lambda, T). FALSE skips them entirely; no oviposition data are then required.

Details

The intermediate results are passed on internally, so nothing is computed twice: s_xj first, then l_x, F_xj and m_x, then r and R0, and finally lambda = exp(r) and T = log(R0) / r.

Value

A named list with elements N, F, sxj, lx, fxj, mx, ex, R0, r, lambda and T With fecundity = FALSE (or when no oviposition data are supplied), fxj and mx are NULL and F, R0, r, lambda, T are NA_real_.

See Also

The individual calc_* functions; lifeTable_calculate for the batch workflow.

Examples

f <- system.file("extdata", "lifetable_example.csv", package = "insectecol")
lt <- lifeTable_read(f)
results <- lifeTable_calculate_all(lt)
results$R0
lifeTable_calculate_all(lt, fecundity = FALSE)$N
