Yes, that makes sense. Thanks!

Ok, I got this point wrong from ?plotmath .

*>> legend(legend = c(expression(paste(L(y, "|", mu)))), x = "bottomleft")
*

*>correct

> What's wrong with the braces?`

They are not the same as in previous cases. They are not "bold".

> What you really want is:

*> legend(legend = c(expression(L(group("", y, "|") * mu))),
**> x = "center")
*

Yes, that is what I want. Thanks!

I got additionally response from Roger D. Peng, which stated:

*> How about
**> legend(legend = expression("L(y | " * mu * ")"), x = "topleft")
*

That's also OK, but note above comment about "bold" braces.

Regards, Gregor
