I need to add a special character to a plot in R. The character that I need to add is the letter 'o' with a dash over it (ō). How can I do this? If I wanted to add the character μ to my plot (as in this question), I can type "mu". But what do I type for o-bar (I'm wishing for a repository of special characters in R)?

Try combining expression with the bar
function
plot(1:5,main = expression("This is your Special Character -" ~ bar(o)))
Just to add a little more information, R actually lets you do a lot of cool stuff with plotting symbols. check out ?bar
.
Just some examples you can try by replacing your argument in main, xlab or ylab:
main = expression(sum(x[i], i==1, n))
main = expression(integral(f(x)*dx, a, b))
