Adding texts to boxplot - ggplot2

enter image description here

I would like to manually add text to indicate significant differences on my graphs by adding letters (e.g. a, b and c) over specific locations on my boxplot using ggplot2. So essentially, I want to be able to add text where I want on the plot.

I have added an example of a graph in the picture above. I have entered the letters (a,b,c) manually in Microsoft Word but I would like to be able to do this in R. Can someone please help? Thank you

Alternatively, you can try this. "Data" and "variable" are just names for what you would put in:

ggplot(data,aes(x=variable))+
    geom_boxplot(aes(y=variable2),color="variable")

just add this line to your code:

annotate("text", x = 3, y=10, label = "whatever")

use ggplot(...) + geom_text() from ggplot2.
