fixed the issue. Will look into that further Assuming you stored the plot in p, you could create another data frame like this:
code :
p + geom_text(data = data.frame(Method = levels(my.data.2.df$Method), 
                                Category = "True positives",
                                y = aggregate(Value ~ Method, data = my.data.2.df[my.data.2.df$Category == "True positives", ], FUN = max)$Value,
                                label = paste0("Result ", LETTERS[1:3], " {}")), 
              aes(y = y, 
                  label = label), 
              color = "orange", 
              vjust = -3, 
              fontface = "bold")
f <- function(my.data.2.df, yAdj = .2) {
  tmp <- transform(expand.grid(Method = levels(my.data.2.df$Method), 
                        Filter = levels(my.data.2.df$Filter)),
            Category = "True positives",
            y = aggregate(Value ~ Method + Filter, 
                          data = my.data.2.df[my.data.2.df$Category == "True positives", ], 
                          FUN = max)$Value)
  tmp$label <- paste0("Result ", LETTERS[1:nrow(tmp)], " {}")
  y.adjust <- as.vector(diff(t(aggregate(Value ~ Method + Filter, 
                                         data = my.data.2.df, 
                                         FUN = range)$Value))) * yAdj  
  tmp$y <- tmp$y + y.adjust
  return(tmp)
}

p + geom_text(data = f(my.data.2.df), 
            aes(y = y, label = label), color = "orange", fontface = "bold")

Matplotlib: annotating plots with arbitrary shapes

Matplotlib: annotating plots with arbitrary shapes

should help you out It is indeed possible to add shapes like you describe to at maplotlib axes object. See this example: http://matplotlib.org/examples/shapes_and_collections/artist_reference.html
So you need to do two things:
R - Add string with superscript to faceted plots

it should still fix some issue After some more research, I found the answer.
The key here is to use tildes:
code :
"Trend:~-0.49~mm~year^-1~(p==2.8e-09)"

will be helpful for those in need There is no real need for facets here other than aesthetics (see @LAP's answer), but if you insist on using facets you can do
code :
ggplot(df, aes(x = Category, y = Age)) +
    geom_point() +
    ggtitle('Distribution of Player Age By Category') +
    facet_wrap(~ Category, scales = "free_x")
Adding plots in between faceted plots with ggplot

this will help There is a function grid.arrange() from gridExtra package (nice explanation [here])1. This allows you to take separately plotted plots and then arrange them in a consistent grid and adjust the size of each plot individually if needed. For this to work you would need to plot each one of your facets separately and then pass them to the package.
Assuming that each of your facets is called something like A1 for top left, B4 for bottom left. Your code would look something like this:
code :
grid.arrange(
   grobs = c(Al:B4)
   widths = c(2, 1, 2, 1),
   layout_matrix = rbind(c(1, 2, 3, 4),
                         c(5, 6, 7, 8))
)
Different scale for faceted plots: scale_y_continuous()

I hope this helps . Answer is simple: use scale_y_continuous(labels = abs). Final code looks as follows:
code :
country <- c(1, 1, 1, 1, 2, 2, 2, 2)
age.range <- c("0-4", "0-4", "5-9", "5-9", "0-4", "0-4", "5-9", "5-9")
sex <- rep(c("M", "F"), times = 4)
pop <- c(-8, 9, -9, 8, -88, 99, -99, 88)
pop.pyr <- data.frame(country, age.range, sex, pop)

library(ggplot2)

ggplot(pop.pyr, aes(x = age.range, y = pop, fill = sex)) + 
geom_col() +
coord_flip() +
scale_y_continuous(labels = abs)
facet_wrap(~ country, scales = "free_x")
