Here's another example of my plotmath whipping boy, the Normal

You want "as.expression(b1)", not "expression(b1)". The latter means "the
expression consisting of the symbol b1". The former means "take the object
stored in b1, and convert it to an expression.".
It's not perfect, because you'll end up with "mu - -1.96sigma" (i.e. two
minus signs), but it's closer than what you had.

Hi, Duncan and David
Thanks for looking. I suspect from the comment you did not run the
code.
And I'm certain from your comment that you didn't run my code, or read
the explanation carefully.

The expression examples I give do work fine already. But I
have to explicitly put in values like 1.96 to make them work. I'm
trying to avid that with substitute, which does work for b2, b3, b4,
b5, all but b1. Why just one?
I'm uploading a picture of it so you can see for yourself:

please look in the middle axis.
Why does only b1 not work, but the rest do?
