Usage
pie1(x, labels = names(x), edges = 200,  radius = 0.8, clockwise = FALSE,  init.angle = if (clockwise) 90 else 0,  density = NULL, angle = 45,  col = NULL, border = NULL, lty = NULL,  main = NULL, percentage=TRUE, rawNumber=FALSE,  digits=3, cutoff=0.01,  legend=FALSE, legendpos="topright", legendcol=2,  radius.innerlabel = radius, ...)
Arguments
x
a vector of non-negative numerical quantities. The values in x are displayed as the areas of pie slices.
labels
one or more expressions or character strings giving names for the slices. Other objects are coerced by as.graphicsAnnot. For empty or NA (after coercion to character) labels, no label nor pointing line is drawn.
edges
the circular outline of the pie is approximated by a polygon with this many edges.
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.
clockwise
logical indicating if slices are drawn clockwise or counter clockwise (i.e., mathematically positive direction), the latter is default.
init.angle
number specifying the starting angle (in degrees) for the slices. Defaults to 0 (i.e., "3 o'clock") unless clockwise is true where init.angle defaults to 90 (degrees), (i.e., "12 o'clock").
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.
percentage
logical. Add percentage in the figure or not. default TRUE.
rawNumber
logical. Instead percentage, add raw number in the figure or not. default FALSE.
digits
When set percentage as TRUE, how many significant digits are to be used for percentage. see format. default 3.
cutoff
When percentage is TRUE, if the percentage is lower than cutoff, it will NOT be shown. default 0.01.
legend
logical. Instead of lable, draw legend for the pie. default, FALSE.
legendpos, legendcol
legend position and legend columns. see legend
position of percentage or raw number label relative to the circle.
...
graphical parameters can be given as arguments to pie. They will affect the main title and labels only.
