When an APC-frame has been produced by apc.frame, this
function draws curves or points in the period/cohort part of the frame.
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, ... )The functions return nothing.
vector of x-coordinates.
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

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".
