Some of them are:
* the x and y axis limits are properties of the scales (e.g. +
scale_x_continuous(limits=c(5, 10))
* the tickmark locations and labels are also properties of the scales
(e.g. + scale_x_continuous(breaks=c(5, 10), labels=c("five","ten"))
* the legend position is set by ggopt()
Some of them aren't:
* legend fill and outline colours can only be changed by modifying
the underlying grid object - see the last chapter of the ggplot book
to see how to do this.
