Description

userCoords transfers realtive coordinate values (i.e. values between 0 and 1) to the actual coordinate system of the plot.

Usage

1
userCoords(x = c(), y = c())

Arguments

x

numeric vector(0-1): relative coordinates on the x axis

y

numeric vector(0-1): relative coordinates on the y axis

Details

x and y need to be values between 0 and 1. These values are then mapped to the coordinates used in the current plot.

Value

list with x and/or y component with values in the current coordinate system
