demography (version 2.0)

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 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 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 demogdata
points(..., pch = 1)

Value

None. Function produces a plot

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.
