Hi Roland,

True, but ... Yoda was here.

plot(0:1,0:1, type="n")
text(x=0.5, y=0.5, labels=expression("\u2020"))
text(x=0.4, y=0.6, labels=expression("\u2021"))

?plotmath, sub "Other symbols" ... "Any Unicode character 

can be...."

Regards, Mark.

PS: Works under Windows Vista, but ...

That would be expected to work

(in a UTF-8 locale || on Windows)
&& on a device with Unicode support
&& in a font that has the glyph.

(it works on Windows because we fake much of a UTF-8 locale there).

There is an alternative: dagger _is_ in the standard Adobe character 
set, so this will work as something \206 (untested) in 8-bit Windows 
character sets on windows(), postscript(), pdf() ... devices

As ever, the information asked for in the posting guide helps us give 
a better answer.

Dear all,

I would like to plot the dagger symbol in R (like LaTeX's \dagger).
However, I was unable to do so.

First, I thought maybe dagger actually exists just like the degree
symbol:

plot(0:1,0:1, type="n")
text(x=0.5, y=0.5, labels=expression(degree))

plot(0:1,0:1, type="n")
text(x=0.5, y=0.5, labels=expression(dagger))

However, this was not very successful. New hope emerged that I will
succeed when I read the help page (as so often) for ?plotmath.
There I discovered the 'symbol' thing and read that the 

Adobe Symbol

font encodings are used. The closest thing I could fine, 

though, was:

plot(0:1,0:1, type="n")
text(x=0.5, y=0.5, labels=expression(symbol("\247")))

But this is obviously not a dagger and it seems the Adobe 

Symbol font

does not have a dagger.

But the Adobe Standard encoding does.

We also know this :-D

library(fortunes)
fortune("Yoda")

So maybe someone can give me some advice?

Thanks in advance,
Roland
