plot-mdt-missing-method: Plot a multiple decrement table

In lifecontingencies: Financial and Actuarial Mathematics for Life Contingencies

Plot a multiple decrement table

Description

S4 method for the plot generic: visualises the decrement structure of an mdt object. Three views are available: a stacked-area chart of death counts d^{(j)}_x (default), a stacked bar chart, or a line chart of decrement probabilities q^{(j)}_x = d^{(j)}_x / l^{(\tau)}_x.

Usage

## S4 method for signature 'mdt,missing'
plot(x, y, type = c("area", "bar", "probability"), ...)

Arguments

x	An mdt object.
y	Not used (kept for S4 generic compatibility).
type	Character: one of "area" (default), "bar", or "probability". "area" and "bar" show stacked decrement counts; "probability" shows decrement-specific probabilities as lines.
...	Further arguments (currently unused).

Value

A ggplot2 object (returned invisibly).

Examples

valdezDf <- data.frame(
  x = 50:54,
  lx = c(4832555, 4821937, 4810206, 4797185, 4782737),
  heart = c(5168, 5363, 5618, 5929, 6277),
  accidents = c(1157, 1206, 1443, 1679, 2152),
  other = c(4293, 5162, 5960, 6840, 7631))
valdezMdt <- new("mdt", name = "ValdezExample", table = valdezDf)
plot(valdezMdt)
plot(valdezMdt, type = "bar")
plot(valdezMdt, type = "probability")
