I think the nearest you can get using only OOo's Math is a horizontal dash 
overprint obtained by using "overstrike R", so your formula would be "(x,y) 
overstrike R". The "overstrike" command is one of the "attributes" shown on 
the web page I cited in a previous post 
(). 
Of course, you can use any letter, or even a sequence of letters, in place 
of "R". So, for example, "overstrike aBc" puts a *continuous* horizontal 
dash through the sequence "aBc".


One thing you could do is provide a footnote to the first use of this 
notation in your document to explain what it means.

Requests For Enhancements (RFE's) are made through the bug tracker at:
http://qa.openoffice.org/
They get treated the same way as bugs that need fixing innitaly.

But you may want to raise the issue first on the dev mailing list:
http://www.openoffice.org/mail_list.html
Discuss the discrepancies you are seeing as mentioned on another post.

About those discrepancies - you said:
> ...the rendering is erratic (maybe because of Windows?). In my system, 
sometimes xR̸y ends with "x" and "y" mixed at the same position, *before* 
the "R̸" (!).
Try double-insulating the "R̸" with a formula something like "x{{ "R̸"}}y - it 
may or may not help. Unfortunately i am also on Linux and so cannot emulate 
your discrepancies until i try it at work tomorrow.

There is no specific project for Math but is does come under the Writer 
project:
http://wiki.services.openoffice.org/wiki/Writer
There does not seem to be much activity on Math at present. I cannot find a 
specific mailing list for this project either.

HTH

By the way, with your new found math expertise you may like to consider 
contributing back on this list when a specialist math issue comes up or 
contributing directly to the above project from your math background. Pay it 
forward ;)

Never mind. You have already helped a lot.

My guess is that OOo Math hasn't this feature at all. :-( I tryed even LyX, and
that was able to do what I want, but, at least to me, in a cumbersome way.

Would it be useful to go to another group where some kind of OOo wish-list is
kept? If this is the case, which group would be that?

Thank you very much.

Very close. Unfortunately, it seems unavailable inside Math.

Maybe someone else could came to the rescue?

Yes, it is what I mean! :-)

Forgive my bad use of words (not a native English speaker). I thought that
*over* would be clear, incontrast to *above*.

I've tried to send a *visible* example, but my posts with attachment haven't
reach the group.

InBetweener,

Your original question was (I quote):
=
I'm somewhat familiar with Microsoft Equation Editor (inside MS Word). Few
days ago, I started using OpenOffice Math. I liked it
very much, but I can't do some things with it. For example, with MS EE, if
I'd like to say that (x,y) in R I did write xRy, which
may be done with OO Math alike. But MS EE allows me to say that not (x,y) in
R by writing xR/y, but with the slash *over* the R. By
the way, this effect of "slashing" can be done with almost any letter or
symbol in MS EE. I simply don't know how to get the same
effect with OO Math.
=

Note in particular your words "but with the slash *over* the R" (my
emphasis). Now it seems that what you really mean is "a slash *through* the
R" similar, for example, to the symbol used for American cents which is a
lower case "c" with a slash *through* it. Is this what you mean? If not,
please post a *visible* example.

Forgive me for such pain. :-) I didn't know that it would be that
difficult to find it on the internet. Textbooks use this, like mine:
"Teoria Elementar dos Conjuntos", by Edgard de Alencar Filho, 19th
Edition, 1980, Livraria Nobel S.A. The title translation is something
like "Elemental Set Theory", or even "Naive Set theory". I'm almost sure
I've seen this same notation inside other works, but I have none with me
at this moment. For now, I've just found someone else who wants the same
I want, but in LaTeX:
http://en.wikipedia.org/wiki/Talk:Binary_relation#Relation_negations_in_LaTeX.



One _singular_ visual example would suffice. At a guess i would
say you are looking for something like a diagonal slash across a
capital R by
your decription but this has not been made clear.


This is "exactly* what I want. But it could be a diagonal slash across
anything I may need. And some times I really need.


AFAIK, options in OO.o are:
"acute{R} bar{R} breve{R} check{R} circle{R} dddot{R} ddot{R} dot{R}
grave{R}
hat{R} overline{R} overstrike{R} tilde{R} vec{R} widehat{R} widetilde{R}
widevec{R} setr" all of which work on my version. You are welcome to
copy and
paste and see if any of these work for your purpose.


Thanks for the list. Microsoft Equation Editor is somewhat longer in the
category "attributes". I have even tried to convert an MS equation into
an OO.o document. I got a bit distorted figure, but everything in place.
When I try to edit the converted equation, several "attributes" are lost
even before I change anything. :-(

I've just installed MathType and its list is even longer. It has even
two options to "negate" any symbol. But one of them seems to have no
translation to any other math "language".


If this is not acceptable then realise that the equation editor in
Microsoft
Office is a cut-down version of the stand-alone specialist tool
MathType by
DesignScience and that MathType allows you to cut and paste to OO.o or
Office
among others. Neither Ofice nor OO.o as "general office productivity
suites"TM are designed to suit every niche market.


I will try to use standalone MathType and see the results. But I really
would prefer to stick at OO.o alone. But I think that the feature I'm
looking for simply doesn't exist. Maybe it could be put into a whish
list...

.
.
.

Ok, I've spent some time trying MathType. It allows me to copy its
equations to other applications, so, if it is not possible to send a
visual example, maybe someone can paste the examples below into the
respective applications in order to see what I'm talkning about.

- Plain TeX:
$$\eqalign{
& x\not Ry \cr
& x\not Fy \cr
& x\,\not \equiv y \cr
& \not \exists x:x \ne x \cr} $$

- LaTeX 2.09 and later:
\[\begin{array}{l}
x\not Ry \\
x\not Fy \\
x\,\not \equiv y \\
\not \exists x:x \ne x \\
\end{array}\]

- Math and Physics Web Forum:
[math]\begin{array}{l}
x\not Ry \\
x\not Fy \\
x\,\not \equiv y \\
\not \exists x:x \ne x \\
\end{array}[/math]

- Wikipedia (I've tested: bad rendering, except for & \not{\exists
}x:x\ne x \\
):
\begin{align}
& x\not{R}y \\
& x\not{F}y \\
& x\,\not{\equiv }y \\
& \not{\exists }x:x\ne x \\
\end{align}

Ok, I think it's enough. My next post will try *again* to send an image.
If it the newsgroup doesn't allow that (the mos likely), is there a way
of sending the .gif to all of you who want to *see* what I'm looking for?

Thanks a lot, Michael.


If I understand you correctly, you are looking for something like the 
"not equal to" symbol (≠)  except that you want to be able to put the 
slash mark on any character or symbol.  By the way, the ≠ symbol can be 
found in Writer in the mathematical operators subset under 
Insert/Special Character.  There is probably some way to over-strike any 
character with the slash, but I don't know how to do it.


Also in Writer, under Format/Character/Font Effects/Strikethrough/with / 
 will put three slashes through the character.  Perhaps someone knows 
how to change that to only one slash.

I'm not a mathematician but the page you cite does not seem to include any
notation for a "not in" that involves any modification of the symbol
representing the relationship (the "R" in your example).

Also, I curious as to what a "slash over the R" (your original question)
actually looks like. Do you mean it looks like an R with an acute accent
over it? A grave acccent? A tilde? What *exactly*?

You might like to try "grave R" or "acute R" in your Math formula.

There's a list at <
http://wiki.services.openoffice.org/wiki/Documentation/OOoAuthors_User_Manual/Writer_Guide/Math_commands_-_Reference>
under "Attributes".

These are the ones I think miight be of interest to you

means). For example,

P equiv Q

might be negated (and *may* in MS Word) writing

P "slash" equiv Q

even if there is no predefined symbol do negate the equivalence.

Have I been clear?

Is there a "hidden" way of doing that in OO Math?

This "slash" feature allow to graphically "negate" any symbol (whatever it
means). For example,

P equiv Q

might be negated (and *may* in MS Word) writing

P "slash" equiv Q

even if there is no predefined symbol do negate the equivalence.

Have I been clear?

Is there a "hidden" way of doing that in OO Math?

Thanks again.

Re: [users] Re: OpenOffice Math: how to "slash" a symbol?

[Daniel Lewis]

 Let me see if I understand what you want to do.  You are use to 
writing  xRy to mean that the ordered pair (x,y) is a member of the 
relation R. For example, let the relationship R be the square function: 
y=x². Then (2,4), (3,9), and (4,16) are all members of this relation. In 
OOo's Math this would be written as (2,4) in R,  (3,9) in R, and (4,16) 
in R. Math replaces the "in" with an epsilon.  Similarly, (5,21) notin R 
states that the ordered pair (5,21) is not in the relationship defined. 
Math replaces the "notin" with an epsilon having a forward slash through it.
 If I understand the use of xRy in MS Word, it refers only to 
relations that are binary. Math on the other hand allows for relations 
which includes three or more variables as in (x,y,z) in R, (w,x,y,z) in 
R, etc.
 Perhaps this will help. Otherwise, you need to be very specific as 
to what xRy means in MS Word.

I'll try to clarify. "R" stands for any relation, not the set for reals.
It could be "S" or any other letter. See below:

x in y
x notin y

The difference between the two lines is that the last shows a slash over
the "in" (or "belongs"?) symbol. Similarly:

x=y
x<>y

The second line shows a "slashed" equal sign, which means "unequal".

I'd like the same effect:

xRy
x"not R"y

Of course, the last line doesn't work, but what I need a "slashed" R
between x and y.

Is it possible?

Thanks again.
