Theming

Besides showing / hiding specific elements, colors, fills, transparency (alpha), and linetypes and sizes can be changed easily using the vpc_theme argument and function. More general plot theming can be accomplished by supplying a ggplot2 theme to the ggplot_theme argument.

vpc(sim, obs,
    vpc_theme = new_vpc_theme (list(
       sim_pi_fill = "#aa6666", sim_pi_alpha = 0.15,
       sim_median_fill = "#66aa66", sim_median_alpha = 0.3,
       obs_ci_color = "red", obs_ci_linetype = 'solid',
       bin_separators_color = NA))
)

If you'd like to add additional lower-level theming using ggplot-elements, you can just use the standard theming features available in ggplot2, e.g.:

vpc(sim, obs) + theme_bw()
