Transform coordinates into proportions of the figure or plot region.
Function for positioning a legend or label in or outside the plot region based on proportion of the plot region rather than Cartesian coordinates.
getProps(pos, side = 1, output = "p")
pos |
A number indicating the coordinates on the x- or y-axis. |
side |
Which axis to choose: 1=bottom, 2=left, 3=top, 4=right. Default is 1. |
output |
Which proportion to take: with respect to the plot region (input 'p', default), or with respect to figure region (output 'f'). |
