pie.labels: Place labels on a pie chart

In plotrix: Various Plotting Functions

Place labels on a pie chart

Description

Places labels on a pie chart

Usage

 pie.labels(x=0,y=0,angles,labels,radius=1.05,bg="white",border=TRUE,
  minangle=NA,boxed=FALSE,explode=0,...)

Arguments

x,y	x and y position of the center of the pie chart
angles	A numeric vector representing angles in radians. This is the return value of ‘⁠floating.pie⁠’.
labels	Text strings to label each sector.
radius	The radius at which to place the labels in user units. The default is 1.05.
bg	The color of the rectangles on which the labels are displayed.
border	Whether to draw borders around the rectangles.
minangle	Minimum angle between labels.
boxed	Whether to use ‘⁠text⁠’ or ‘⁠boxed.labels⁠’ to display the labels.
explode	How much the pie chart has been "exploded".
...	Arguments passed to ‘⁠text⁠’ or ‘⁠boxed.labels⁠’.

Details

Labels may be placed within the pie (radius less than the pie radius), on the edge or outside as in the examples below. If within the pie, it is probably best to use ‘⁠boxed=TRUE⁠’.

If some labels overlap, passing a value in radians for ‘⁠minangle⁠’ may be used to spread them out.

Value

nil

Note

Remember that ‘⁠x⁠’ and ‘⁠y⁠’ specify the center of the pie chart and that the label positions are specified by angles and radii from that center.
