Re: [R] transforming output of grid.locator() to coordinates of a leaf viewport

Paul, Thanks very much! Your example code below shows exactly how to do what I wanted. -Ben p.s., For the record, transRight - current.transform() after the second call to pushViewport() seems to have gotten deleted from you example code below, but that was obvious. -Original Message-

Short form: How do I transform the output of grid.locator() (or grid.locator(unit='npc')) to the native (or npc) coordinates of a viewport other than the top-level viewport? Thanks in advance. -Ben Long form: I would like the user to be able to
