Depths of paths are pretty straightforward because they contain no branchings. The depth of a viewport stack is the sum of the depths of the components of the stack. The depth of a viewport tree is the depth of the parent plus the depth of the children. The depth of a viewport list is the depth of the last component of the list.
An integer value.
vp <- viewport()
depth(vp)
depth(vpStack(vp, vp))
depth(vpList(vpStack(vp, vp), vp))
depth(vpPath("vp"))
depth(vpPath("vp1", "vp2"))
