Hi:
I'm not sure what you mean by line weight - I interpreted it to mean size,
but you already have have it in your geom_line() call. If you want thicker
lines, increase size. As for the others, try this:
ggplot(ddata, aes(x = area, y = disc, colour = year)) +
geom_point() + geom_line(aes(group = year), size = 1) +
scale_y_continuous(name='Percent Well Prepared', limits=c(0, 100)) +
scale_colour_discrete('Year') + xlab('') +
opts(axis.text.x = theme_text(size = 16)) +
opts(axis.text.y = theme_text(size = 16)) +
opts(legend.title = theme_text(size = 12, hjust = 0)) +
opts(legend.text = theme_text(size = 12))
Brandon Hurr has taken the time to organize a nice wiki to illustrate how to
use different sets of opts():

Click on the 'Usage Examples' link under the subsection title to get to the
good stuff.
Thank you for providing a data frame in dput() form - it simplified matters
greatly!
HTH,
Dennis
