grid.copy {grid} | R Documentation |
Grid graphical objects are references to list structures, which means that copies of graphical objects “point” to the same list structure.
This function copies graphical objects by value, which means that the copy “points” to a separate list structure.

## Create a graphical object l <- grid.lines(draw=FALSE) ## View the list.struct grid.get(l) ## Copy by reference l2 <- l ## Edit the common list.struct grid.edit(l2, gp=gpar(col="green")) ## We have modified "l" grid.get(l) ## Copy by value l3 <- grid.copy(l)
