Suppose I have a plot

And I want some text to indicate a Normal distrubition. I could do
this:
text(5, 6, substitute(X~~~~N(mu, sigma^2)), adj = 0)
text(5.35, 6, "~", adj = 0)
But that's clumsy, and depending on your plotting device, might not
even look
sensible. I'd prefer to be able to do it more directly and
simply the way these do:
text(5, 1, expression(X %~~% N(mu, sigma^2)), adj = 0)
text(5, 2, expression(X %prop% N(mu, sigma^2)), adj = 0)
text(5, 3, expression(X %=~% N(mu, sigma^2)), adj = 0)
They're easy, but they don't give a single tilde. I know how to put a
tilde(X) or even a wide tilde, but there're not it either.
What did I miss?
Does this do it?
text(2, 3, expression(X *"~"* N(mu, sigma^2)), adj = 0)
