Table to TEX

[EViews Esther]

This thread is about the new version of tbl2tex add-in that converts a EViews table into LaTex-type table.

Please note that fancy styles (e.g. color/symbols/characters) and the line between header and content cannot be created.
However, we would like to actively continue working to better integrate LaTex in EViews.

[Change log]

• 2011/02/10 Special characters (e.g. # & % $ ~ _ ^ { }) are controlled.
• 2011/05/24 Additional special character \ (backslash) is controlled.

Hi Esther,

I just took a look at your code and I wonder, since this is only for tables, wouldn't it be better if you make it into a table proc instead of a global one? Besides, it would require users to actually click on the table first before running the program (to get input for the _this command), maybe global is not the best idea. Just a thought.

Mistake in the installer. It actually works from _this, so yeah it should be a table proc. We'll update the installer.

[EViews Esther]

The install program is updated.

the "&" is not filtered!

for example

Code: Select all

%ex7 = "\Example Files\EV7 Manual Data"
%ch28 = "\Chapter 28 - Quantile Regression"
%wf = @evpath + %ex7 +%ch28 +"\engel.wf1"
wfopen %wf

equation eq00.qreg y c x
freeze(tb0) eq00.output
tb0.tbl2tex(name="tb0",path="e:/")


in the tex file, the line

Code: Select all

Huber Sandwich Standard Errors & Covariance


the character "&" should be changed to "\&"

[EViews Esther]

Yes. You are right. Whenever we use one of the following special characters,

# & % $ ~ _ ^ { } \

we need to include a \ in front of the character.

Let me think about how to deal with these special characters.

Hi,

I think the following works.

Replace:

Code: Select all

%special = "# & % $ ~ _ ^ { } \"
for !r=1 to !nrows
   for !c=1 to !ncols
      %temp = {%tbl}(!r,!c)
      for !i=1 to @wcount(%special)
         %cha = @word(%special,!i)
         if @wfind(%temp, %cha) then
            %cha1 = "\"+ %cha
            %temp = @replace(%temp, %cha, %cha1)            
         endif   
      next


with:

Code: Select all

%special = "# & % $ ~ _ ^ { }" '\"
for !r=1 to !nrows
   for !c=1 to !ncols
      %temp = {%tbl}(!r,!c)
      for !i=1 to @wcount(%special)
         %cha = @word(%special,!i)
            %cha1 = "\"+ %cha
            %temp = @replace(%temp, %cha, %cha1)            
      next


Change amounts to dropping "\" from list of special characthers and dropping the if-statement (which seems unnecessary). Maybe the @wfind, which should return position of character, doesn't work (Haven't checked).

About dropping "\". If the code encounters "\" then it would create "\\" which is a linebreak, which is not what you want. I'm not sure you really will use "\" that often that it is a big problem. If you want "\" in the list you have to add a special condition for that character (I think).

Yes. @wfind should be replaced to @instr when we want to find the position of characters.
However, as you mentioned, the step to check whether special characters are found can be ignored.

About dropping "\". If the code encounters "\" then it would create "\\" which is a linebreak, which is not what you want. I'm not sure you really will use "\" that often that it is a big problem. If you want "\" in the list you have to add a special condition for that character (I think).

We can keep the list for special characters by adding an additional condition - i.e. if %cha = "\" then - as follows.

Code: Select all

%special = "# & % $ _ { } \ ~ ^"
for !r=1 to !nrows
   for !c=1 to !ncols
      %temp = {%tbl}(!r,!c)
      for !i=1 to @wcount(%special)
         %cha = @word(%special,!i)
         if %cha = "\" then
            %temp = @replace(%temp, %cha, "$\backslash$")            
         else
            %temp = @replace(%temp, %cha, "\" + %cha)                        
         endif
      next

it seems that the download page http://www.eviews.com/Addins/addins.shtml has not been updated for this addin

[EViews Gareth]

What do you mean?

[CharlieEVIEWS]

Perhaps I am doing something wrong here (using TeXWorks) but the compiled files look seriously disfigured - either when copied into a larger .tex or when run as the .tex produced directly by the add-in. Also, I am experiencing problems with the $\backslash$_ which occurs when you have an underscore in a variable name.

Any help? I am being a moron ? anyway, huge fan of the add-ins guys, keep up the great work.

[tzink]

The output of this add-in doesn't compile for me. Errors are due to the fact that special characters aren't properly dealt with. For instance, the produced code snippet:

Equation: LN$\backslash$_S$\backslash$_P = P(1) + P(2)*LN$\backslash$_P$\backslash$_CU + P(3)*LN$\backslash$_P$\backslash$_FUEL + P(4) \\

results in the error:
! Missing $

The problem is that the underscores in my variables names are not filtered properly by the $\backslash$ command. I don't know enough about EViews programming to suggest a solution, unfortunately.

Has anyone on the dev team looked at GRETL's implementation? The Latex integration in GRETL is flawless, IMO.
