Yes, you are right.  I meant panels,   xyplot generates 22 panels, which one with y-axis, x-axis and a title.  I need to change the font size of title in the panels.

There being no "subplot" in lattice, I'm guessing that you mean "panel" for that term,  and the "title" is in fact the strip annotation, but I am finished with throwing out guesswork solutions until clarity is established.

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?
