I am creating a Gviz plot with some particularly long titles in the title panel.

I tried setting title.width wider and using rotate.title however it appears that rotate.title rotates about some point in the title. Possibly the midpoint but clearly not the first character of the title, consequently the beginning of the titles is being cut off by the outer margin.

I was wondering if the is an parameter along the lines of offset.title that would let me translate them to the right?

The title is supposed to be "adult endothelial progenitor cell"
