main = "rpois(100, lambda = 5)")
## Simple quantiles/ECDF, see ecdf() {library(stats)} for a better one:

Examples
### Adding objects to a ggplot object
p <- qplot(wt, mpg, colour = hp, data = mtcars)
p + coord_cartesian(ylim = c(0, 40))
p + scale_colour_continuous(breaks = c(100, 300))
p + guides(colour = "colourbar")
# Use a different data frame
m <- mtcars[1:10, ]
p %+% m
### Adding objects to a theme object
# Compare these results of adding theme objects to other theme objects
add_el <- theme_grey() + theme(text = element_text(family = "Times"))
rep_el <- theme_grey() %+replace% theme(text = element_text(family = "Times"))
add_el$text
