Description
Determine the number of levels in a viewport stack or tree, in a viewport path, or in a grob path.
Usage

## S3 method for class 'viewport'
depth(x, ...)
## S3 method for class 'path'
depth(x, ...)
Arguments
x |
Typically a viewport or viewport stack or viewport tree or viewport list, or a viewport path, or a grob path. |
... |
Arguments used by other methods. |
Details
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.
Value
An integer value.
