Dear R users,
I am having issues finding a special character (and how to insert it) in the
lab of a graph axis.
Let us say that the label of my axis is "X", i would like the X to have a
"line" over it, indicating that it is the "mean of X values" (i don't even know
how to properly state that in english...). Does someone understand, and have
any idea about how to do that?
Greetings,
R.H
