A function to plot pie graphs as a glyph
This function allows the user to plot a pie graph at a specified x/y location in a plotting region.
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 |
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 |
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 |
border, lty |
(possibly vectors) arguments passed to
|
main |
an overall title for the plot. |

graphical parameters can be given as arguments to
