Avi,

I've designed and used multiple boxplots in many projects. They might show
geochemical concentrations at two locations or in two (or three) separate
time periods. All data in a single dataframe.

What I need to plot are multiple 'your_data' sets. I'll be testing this:
ggp <- ggplot(NULL, aes(x, y)) +    # Draw ggplot2 plot based on two data frames
   geom_point(data = data1, col = "red") +
   geom_line(data = data2, col = "blue")
ggp                                 # Draw plot

today, but using four boxplots.
