[R] Plot Title: Adjusting Position

[Rich Shepard]

   Plots of compositional data ternary diagrams do not accept the main label
within the plot() function, but do print the label when it is specified
within the title() function. On some of these plots I need to raise the
position of the title just enough to move the text above the top row of
diagrams.

   Applying the outer=TRUE option moves the title too high; the top half of
the text is cut off from viewing. The help file, ?title, suggests that the
line option applies to sub-titles and axis labels, not the main title.
Setting character expansion to a negative value throws an error.

   How can I either move the main title sightly higher on the figure or
slightly reduce the text size so the title does not overlap part of the
ternary diagrams?
