to label the axis in a ggplot2 in R with the derivative of Q, i need the character "Q with overdot" --> "Q̇"

is there a library or anything to integrate special characters like this?

CodePudding user response：

I could not find a unicode code for Q̇, but you can use expression(dot(Q)), even though the dot may not be centered.

plot.new()
title(main = expression(dot(Q)))

CodePudding user response：

There is no unicode character for Q-dot. An interesting read about that can be found here:
