Hello

Many thanks.

par.main.text is the main title (on top of all plots).  I need to change the each of the titles in the, say, subplots.

The results are very nice and help me to understand what is going on with the data. However since the names (labels of each variable) within the xts variable are large, the title of each plot is cropped.   How can I select the font size of the titles without changing all other fonts?
