userCoords: Transfer relative to actual plot coordinate values
In JBTools: Misc Small Tools and Helper Functions for Other Code of J. Buttlar

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

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

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

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

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