- The argument to give dev.new is 'height', not 'length'.
- There are two margins, an inner margin (controlled by `mar`) and an outer
margin (controlled by `oma`).
- The link to the dropbox image does demonstrate that you are having problems
with your ggplot efforts, but it wasn't a link to any test data or the code
used to produce that tree, so I'm not in a position to do any testing to offer
refinements. From the red/bold highlighting in the HTML copy I got directly
(that none of the other viewers are seeing) I can see you are frustrated, but
you need to take responsibility for writing a message that is being mangled. We
readers of the this plain-text-only mailing list were seeing it.
- Please read the Posting Guide about the need to information about your
specific computer setup and the value of a reproducible example. I suggest you
should be learning to use the png or pdf devices. Read ?Devices and ?png. (The
default units are not inches.).

- It appears that your second message was also sent as HTML. I do therefore ask
(again) that you take the time to read the Posting Guide.
