corner.label {plotrix}

Find corner locations and optionally display a label

Description

Finds the coordinates in user parameters of a specified corner of the figure region and optionally displays a label there

Usage

 corner.label(label=NULL,x=-1,y=1,xoff=NA,yoff=NA,figcorner=FALSE,...)

Arguments

label

Text to display. The default is to display nothing.

x

an integer value: -1 for the left side of the plot, 1 for the right side

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.

figcorner

Whether to find/display at the corner of the plot or figure.

...

further arguments to the ‘⁠text⁠’ command for the label

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.

Value

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