Plot a PolySet as polylines.
1 2 3 4 
polys 
PolySet to plot (required). 
xlim 
range of Xcoordinates. 
ylim 
range of Ycoordinates. 
projection 
desired projection when PolySet lacks a

plt 
four element numeric vector 
polyProps 
PolyData specifying which polylines to plot and their
properties. 
lty 
vector describing line types (cycled by 
col 
vector describing colours (cycled by 
bg 
background colour of the plot. 
axes 
Boolean value; if 
tckLab 
Boolean vector (length 1 or 2); if 
tck 
numeric vector (length 1 or 2) describing the length
of tick marks as a fraction of the smallest dimension. If

tckMinor 
numeric vector (length 1 or 2) describing the length of tick marks as a fraction of the smallest dimension. These tick marks can not be automatically labelled. If given a twoelement vector, the first element describes the tick marks on the xaxis and the second element describes those on the yaxis.

This function plots a PolySet, where each unique (PID
,
SID
) describes a polyline. It does not connect each polyline's
last vertex to its first. Unlike plotMap
, the function
ignores the aspect ratio. It clips polys
to xlim
and
ylim
before plotting.
The function creates a blank plot when polys
equals
NULL
. In this case, the user must supply both xlim
and
ylim
arguments. Alternatively, it accepts the argument
type = "n"
as part of ..., which is equivalent to specifying
polys = NULL
, but requires a PolySet. In both cases,
the function's behaviour changes slightly. To resemble the
plot
function, it plots the border, labels, and other
parts according to par
parameters such as col
.
For additional help on the arguments lty
and col
, please
see par
.
PolyData consisting of the PolyProp
s used to create the plot.
To satisfy the aspect ratio, this plotting routine resizes the plot
region. Consequently, par
parameters such as
plt
, mai
, and mar
will change. When the function
terminates, these changes persist to allow for additions to the plot.
