Convert between Graphics Coordinate Systems
Convert between graphics coordinate systems.
numeric vector of coordinates.
character strings giving the coordinate systems to convert between.
The coordinate systems are
the device coordinate system.
normalized device coordinates.
normalized figure coordinates.
normalized plot coordinates.
normalized inner region coordinates. (The ‘inner region’ is that inside the outer margins.)
(These names can be partially matched.) For the ‘normalized’ coordinate systems the lower left has value 0 and the top right value 1.
Device coordinates are those in which the device works: they are
usually in pixels where that makes sense and in big points (1/72 inch)
A numeric vector of the same length as the input.
