In gridGeometry: Polygon Geometry in 'grid'

Generate Grobs from Coordinates

Description

This function generates a grob from a set of coordinates (a list of (x,y) lists).

Usage

xyListToPath(x, rule=, name=NULL, gp=gpar())
xyListToPolygon(x, name=NULL, gp=gpar())
xyListToLine(x, name=NULL, gp=gpar()) 

xyListPath(x, rule, name=NULL, gp=gpar())
xyListPolygon(x, name=NULL, gp=gpar())
xyListLine(x, name=NULL, gp=gpar()) 

Arguments

x	A set of coordinates (e.g., from polyclip or trim).
rule	A fill rule: "winding" or "evenodd".
name	A name for the resulting grob.
gp	Graphical parameter settings for the resulting grob.

Details

Following the addition of the xyListFromGrob function, the *To*() forms are preferred.

Value

The result is a grob.
