label and ref in latex export

label and ref in latex export

[Manish]

Hello,

How do I refer to labels created for tables and figures in Org mode so
it appears in LaTeX export?

Currently I am using a BEGIN_LaTeX and END_LaTeX to enclose \ref like
so.  I am sure this is not how it was intended to be used but I couldn't
locate anything in documentation.

,----
| Please see figure
| #+BEGIN_LaTeX
| \ref{fig:results}
| #+END_LaTeX
|
| #+CAPTION: Business Transaction over Business Units
| #+LABEL: fig:results
| [[./xxxxx.png]]
| #+ATTR_LaTeX: scale=0.7
`----

Thanks,
-- 
Manish

Just write \ref{fig:results} anywhere in the text and you should be  
fine.

And the ATTR_LaTeX: has to be *before* the link to the figure.

I did not realize that I could put that literal LaTeX in text which can
then be processed by PDFLaTeX.

Yes, I switched it by mistake while creating the example.

Thank you.

label and ref in latex export

[Vikas Rawal]

The following has been taken from my org file.

-------------

#+CAPTION: Average output, cost and net income per acre, by area, (2005-06 prices)
#+LABEL: tab:avprofit
#+ATTR_LATEX: table * tabulary width=\textwidth align=l|RRRR
#+BEGIN_SRC R :results value raw :colnames yes :hline yes
  subset(a,Crop_group=="Paddy")->a
  a[,c(8:10)]*a[,6]/a[,7]->a[,c(8:10)]
  vtab1(a,8,10,1,wtd.mean)->a1
  round(as.numeric(as.character(a1[,2])))->a1[,2]
  round(as.numeric(as.character(a1[,3])))->a1[,3]
  round(as.numeric(as.character(a1[,4])))->a1[,4]
  names(a1)<-c("Area","output","Cost","Net income")
#+END_SRC

\ref{tab:avprofit} shows that the average levels of are highest in
Area 7.

------------------

When I export it to latex/pdf, \ref{tab:avprofit} is just shown as ??.
What am I not doing correctly? 

Also, is it okay if the text where the table is referenced comes
before the table (and therefore its label) itself?

Aloha Vikas,

Perhaps "table *" -> "table*"?

All the best,

I have corrected that. But it still says "Exporting to PDF...done, with some
errors: [undefined reference]"

The warning [undefined reference] seems to be on account of not
finding the label reference.

You might want to check the .tex file to see if the label is there.
Also, compiling with LaTeX yields a detailed log, which will tell you
the line number of errors and warnings. You could look there to pinpoint
the error(s).

I was using this in the preamble:
#+LaTeX_HEADER: \usepackage[hmargin=3cm,vmargin=3.5cm]{geometry}

This was conflicting with my use of tabulary. I remove this line and
the errors disappeared.

Thanks very much for pointers.
