Perhaps you should do a google search on the topic of getting umlauted characters for the distro of your choice? >Well, Linux is not Mac. For which I am everlastingly thankful. I believe the following works on both Fedora and Ubuntu: (1) First add/set a "compose" key: In my current system (Ubuntu 16.04.2; Mate Desktop 1.12.1) the sequence of clicks is: System -> Control Center -> Keyboard -> Layouts -> Options -> Position of Compose key -> [e.g.] Left Win Clicking on "Left Win" inserts a tick mark in the little white box. On my keyboard the "Left Win" key is to the left of the "Alt" key, which is to the left of the space bar. It displays the (yeuchh!!!) Windoze symbol, a distorted window in black and white. This key is totally useless for anything else, so one might as well use it for the compose key. (2) Then do: <compose key> <letter> <accent>. E.g ' <compose key> a " ' gives ' ? '. Note: Do *not* hold the compose key down while pressing the other keys. Press the compose key and release it; then press "a" (nothing appears) then press ' " ' --- and bingo, ? appears. HTH cheers, Rolf Turner P. S. Of course you just need to do the "set a compose key" bizzo *once* and then it is set and works forever more. Until you change or bugger up your OS. :-) R.

Hi
I just had to do something similar in windows with \"{u}. Try Unicode
symbol
- see ?plotmath
ggplot(data, aes(x=X)) + geom_line(aes(y = Z), size=0.43) +
xlab(expression(atop(top,bold(Age~"\u00e4"))))

I am sorry, I use a linux operating system. I use Fedora 25 but the student
I wanted to show this uses Ubuntu, though I don't know if the distribution
matters.
Thanks again for your help, and best wishes,

Thanks, Duncan! This works for the particular case and is, to my mind, a great solution! However, I was wondering: is it possible to use these double dots with another character, such as omega? I apologize for changing the question somewhat, but I did not realize earlier that there were separate codes for putting double dots over different letters and I thought that figuring out the simpler question would be enough for me to figure out the next step.
