Hi,
Is it possible to display double dot (umlaut) over a character such as would be
possible using \ddot x in LaTeX? I can do this using tikzDevice but I wanted
something simpler to point to.
Here is an example of what I would like to do, but it is not quite there:
require(ggplot2)
data<-as.data.frame(c("a","b","c","a","b","c"))
colnames(data)<-"Y"
data$X<-c(1:6)
data$Z<-c(1,2,3,1,2,3)
ggplot(data, aes(x=X)) + geom_line(aes(y = Z), size=0.43) +
xlab(expression(atop(top,bold(Age~"à"))))
I would like to put in a double dot over the "a" in the x-axis instead of "`".
Many thanks for any suggestions and best wishes,
Ranjan
You haven't told what OS you are using, but with Windows OS, you can get
the 'ä' by making sure the NUMLOCK key is on, hold down the alt key and
press 0228 on the numeric keypad.
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.
On a Mac it is cmd-u followed by the vowel of your choice. 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 ' ä '.
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, ä 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. :-)
