[R] Adjusting Font Size: lattice / bwplot

[Michael Just]

Hello,
If you run the following code with lattice installed:

bwplot(voice.part ~ height, data=singer, xlab="Height (inches)")

There will be some text in the graph e.g. Soprano 1, Soprano 2, etc -
60, 65, etc and the title: Height (Inches).  How can one make the font
for this text larger and/or bold?  Also, is there a way to thicken or
bold the lines of the box and whisker plot?

Thank you kindly,
Michael
