pc.lines

Plot period and cohort effects in an APC-frame.

Description

When an APC-frame has been produced by apc.frame, this function draws curves or points in the period/cohort part of the frame.

Usage

pc.points( x, y, ... )
  pc.lines( x, y, ... )
  pc.matpoints( x, y, ... )
  pc.matlines( x, y, ... )
  pc.matshade( x, y, ... )
  cp.points( x, y, ... )
  cp.lines( x, y, ... )
  cp.matpoints( x, y, ... )
  cp.matlines( x, y, ... )
  cp.matshade( x, y, ... )

Arguments

`x`	vector of `x`-coordinates.
`y`	vector or matrix of `y`-coordinates.
`...`	Further parameters to be transmitted to points, lines, matpoints, matlines or matshade used for plotting curves in the calendar time realm of a graph generated by `apc.frame`

Details

Since the Age-part of the frame is referred to by its real coordinates plotting in the calendar time part requires translation and scaling to put things correctly there, that is done by the functions pc.points etc.

The functions cp.points etc. are just synonyms for these, in recognition of the fact that you can never remember whether it is "pc" or "cp".

Value

The functions return nothing.
