y

an integer value: -1 for the bottom side of the plot, 1 for the top side

xoff,yoff

Horizontal and vertical text offsets. Defaults to one half of the width and height of "m" respectively.

further arguments to the text command for the label

Value

A list of the x and y positions of the corner adjusted for the offsets.

Details

corner.label finds the specified corner of the plot or figure and if label is not NULL, displays it there. The text justification is specified so that the label will be justified away from the corner. To get the label squeezed right into a corner, set xoff and yoff to zero.

Examples

# NOT RUN {
 plot(1:10,1:10)
 corner.label("A")
 corner.label(x=1,y=1)
 corner.label("B",y=-1,x=1,figcorner=TRUE,col="red")
