[R] Producing character "given" i.e. "| " with plotmath

[Gorjanc Gregor]

Hello!

Does someone know how to produce

  L(y|mu)

with plotmath?

Some code with unsuccessfull results:

plot(dnorm(x = seq(from = -4, to = 4, by = 0.1)), type = "l")
## Not what I want
legend(legend = c(expression(L(y:mu))), x = "topright")

## Strange, is this a bug?
legend(legend = c(expression(L(y|mu))), x = "top")

## Group produces an error
legend(legend = c(expression(group(L(y, "|", mu)))), x = "topleft")

## Paste keeps commas in expression
legend(legend = c(expression(paste(L(y, "|", mu)))), x = "bottomleft")

## This one is OK, but braces are not as they should be 
legend(legend = c(expression(paste("L(y", "|", "mu)"))), x = "bottom")

Thanks!

Lep pozdrav / With regards,
    Gregor Gorjanc
