display double dot over character in plotmath?
Hi I looked up for the Unicode version at http://www.utf8-chartable.de/unicode-utf8-table.pl You might have to go to another page to find the Unicode equivalent. You may not be able to get the right character showing and get at square/s instead - it all depends on the drivers and how many characters that make up the Unicode character I had a case of this recently and it did not make any difference using Cairo Regards Duncan -----Original Message----- From: R-help [mailto:r-help-bounces at r-project.org] On Behalf Of Ranjan Maitra Sent: Monday, 15 May 2017 01:44 To: r-help at stat.math.ethz.ch Subject: Re: [R] display double dot over character in plotmath? 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. Thanks again! Best wishes, Ranjan On Sun, 14 May 2017 23:57:50 +1000 Duncan Mackay <dulcalma at bigpond.com> wrote:

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~"?"))))
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 '?' 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. Thanks again for your help, and best wishes, Ranjan
