Place labels on a pie chart
Places labels on a pie chart
pie.labels(x=0,y=0,angles,labels,radius=1.05,bg="white",border=TRUE, minangle=NA,boxed=FALSE,explode=0,...)
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. |
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.
nil
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.
