There are half a dozen implementations of ternary plots in as many R packages so it is hard to be specific. Since you are using title(), try the "further graphical parameters from par" mentioned in the manual page such as adj=c(x, y) for position (or maybe the line= argument) and cex.main= for size.

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?
