Using bquote() to print confidence intervals

I want to use the function bquote() in R to put a confidence interval on a graph. I am able to get the first parenthesis and number, but everything after that is problematic.

For example if I wanted to print the following confidence interval (2,5) then I have the following:

plot(1:5)
lower = 2
upper = 5
mtext(bquote("("~.(lower)))

that gets me half the interval but I can't get the rest of it. I would have thought something like

mtext(bquote("("~.(lower),","~.(upper),")")

would have worked, but it doesn't.

use as.expression to coerce the whole thing into an expression and use * to separate variables from strings

plot(1:5)
lower = 2
upper = 5
mtext(as.expression(bquote("("*.(lower)*","*.(upper)*")")))
