Hi, useR- I want to create a graphic device - e.g., windows() - that only specific function(s) have control over. For example, suppose you run the following code: windows() dv = dev.cur() dv "dv" is the index for the graphic device. By passing "dv" value into a new function, I can control the device. The problem is that other functions (namely, plot) can control that device as well. Does anyone know how to avoid this and achieve exclusive control over a specific device?
