I'm not sure that we share an interpretation of the term "depth" in  
this context. I'm interpreting your request to me vertical alighnment.

Read the help page, especially the paragraph about padj. I will admit

were not what I experienced when I tried alternate versions. It did  
not seem to me that padj=0 produced "top alignment".
