pieGlyph: A function to plot pie graphs as a glyph
In Rgraphviz: Provides plotting capabilities for R graph objects

Description Usage Arguments Author(s) See Also Examples

This function allows the user to plot a pie graph at a specified x/y location in a plotting region.

1	pieGlyph(x, xpos, ypos, labels = names(x), edges = 200, radius = 0.8, density = NULL, angle = 45, col = NULL, border = NULL, lty = NULL, main = NULL, ...)

`xpos`	The x location of the glyph
`ypos`	The Y location of the glyph
`x`	a vector of positive quantities. The values in `x` are displayed as the areas of pie slices.
`labels`	a vector of character strings giving names for the slices. For empty or NA labels, no pointing line is drawn either.
`edges`	the circular outline of the pie is approximated by a polygon with this many edges.
`radius`	the pie is drawn centered in a square box whose sides range from -1 to 1. If the character strings labeling the slices are long it may be necessary to use a smaller radius.
`density`	the density of shading lines, in lines per inch. The default value of `NULL` means that no shading lines are drawn. Non-positive values of `density` also inhibit the drawing of shading lines.
`angle`	the slope of shading lines, given as an angle in degrees (counter-clockwise).
`col`	a vector of colors to be used in filling or shading the slices. If missing a set of 6 pastel colours is used, unless `density` is specified when `par("fg")` is used.
`border, lty`	(possibly vectors) arguments passed to `polygon` which draws each slice.
`main`	an overall title for the plot.
`...`	graphical parameters can be given as arguments to `pie`. They will affect the main title and labels only.
