No, "|" is a logical Operator that can be rewritten in its original function form as follows:

**"|"(FALSE, TRUE)
**
Hence the result is expected.

You have not specified any delimiter.

correct

What's wrong with the braces?`

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