plot.demogdata

Plot age-specific demographic functions

Description

If plot.type="functions", then years are plotted using a rainbow palette so the earliest years are red, followed by orange, yellow, green, blue and indigo with the most recent years plotted in violet. If plot.type="time", then each age is shown as a separate time series in a time plot.

Usage

## S3 method for class 'demogdata'
plot(x, series = ifelse(!is.null(x$rate),
  names(x$rate)[1], names(x$pop)[1]), datatype = ifelse(!is.null(x$rate),
  "rate", "pop"), years = x$year, ages = x$age, max.age = max(x$age),
  transform = (x$type == "mortality"), plot.type = c("functions",
  "time", "depth", "density"), type = "l", main = NULL, xlab, ylab,
  ...)

## S3 method for class 'demogdata'
lines(x, series = ifelse(!is.null(x$rate),
  names(x$rate)[1], names(x$pop)[1]), datatype = ifelse(!is.null(x$rate),
  "rate", ""), years = x$year, ages = x$age, max.age = max(x$age),
  transform = (x$type == "mortality"), plot.type = c("functions",
  "time", "depth", "density"), ...)

## S3 method for class 'demogdata'
points(..., pch = 1)

Arguments

`x`	Demogdata object such as created using `read.demogdata` or `smooth.demogdata`.
`series`	Name of series to plot. Default: the first matrix within `datatype`.
`datatype`	Name of demogdata object which contains series. Default “rate”. Alternative: “pop”.
`years`	Vector indicating which years to plot. Default: all available years.
`ages`	Vector indicating which ages to plot. Default: all available ages.
`max.age`	Maximum age to plot. Default: all available ages.
`transform`	Should a transformation of the data be plotted? Default is TRUE if the object contains mortality data and datatype="rate", and FALSE otherwise.
`plot.type`	Type of plot: either “functions” or “time”.
`type`	What type of plot should be drawn. See `plot` for possible types.
`main`	Main title for the plot.
`xlab`	Label for x-axis.
`ylab`	Label for y-axis.
`...`	Other plotting parameters. In `points.demogdata`, all arguments are passed to `lines.demogdata`.
`pch`	Plotting character.

Value

None. Function produces a plot
