Boxplot and five statistics - plotting quantiles - R

I want to visualize my data using Boxplot.

I have created a boxplot and a stripchar using the follwonig comands: 

  adjbox(nkv.murgang$NK, main = "NKV, Murgang - Skewness Adjusted", horizontal = T, axes = F,
           staplewex = 1, xlab = "Nutzen Kosten Verhältnis")

  stripchart(nkv.murgang$NK, main = "NKV, Murgang - Stripchart", horizontal = T, pch = 1,
             method = "jitter", xlab = "Nutzen Kosten Verhältnis")

However I cannot figure out how to incorporate the corresponding five number statistics into the graph (min, 1st Qu., Mean, 3rd Qu., Max). I want them to be display next to the whiskers.

What is my y-axis in this case?

Additionaly, I also want to highlight the mean and median with different colours. Something like this:

desired output

is it possible to combine this two into one graph?

Thanks for any input. I know this seems very basic, but I am stuck here...

Instead of using adjbox, use ggplot:

There is a trick for the unknown x-axis: x = factor(0). 

  ggplot(nkv.murgang, aes(x = factor(0), nkv.murgang$NK)) +
    geom_boxplot(notch = F, outlier.color = "darkgrey", outlier.shape = 1,
                 color = "black", fill = "darkorange", varwidth = T) + 
    ggtitle("NKV Murgang - Einfamilienhaus") + 
    labs(x = "Murgang", y = "Nutzen / Konsten \n Verhälhniss") +
    stat_summary(geom = "text", fun.y = quantile,
                 aes(label=sprintf("%1.1f", ..y..)),
                 position=position_nudge(x=0.4), size=3.5)

You can combine a boxplot with a point-plot using ggplot2 as follows 

require(ggplot2)
ggplot(mtcars, aes(x = as.factor(gear), y = wt)) + 
  geom_boxplot() +
  geom_jitter(aes(col = (cyl == 4)), width = 0.1)

The result would be:
