You just have to *uncheck* the box "Use AMS math package automatically" and
then check "Use AMS math package" in Document -> Settings... -> Math
Options. Then Apply. Worked for me in LyX 2.0.3 with "article (SPIE
Proceedings)" Document Class.

Re: Using sweave/knitr in master and child documents
If that is the case, yes, you can use child documents. 2.0.x has significant improvements over 1.6.x in terms of Sweave/knitr support, so I strongly recommend you to upgrade.

If that includes environments that shouldn't be in a header (for me, usually a multiline displayed equation), it will choke in this manner. Why it only does that with export to ps2pdf is not clear.

Problem with ps2pdf & pdflatex
I've downloaded a package called classicthesis (http://code.google.com/p/classicthesis/
) & am trying to print their sample document.
I'm getting the error:
Package hyperref Error: Wrong driver option `pdftex'
Tex capacity exceeded, sorry [main memory size=300]
Curiously enough I can export to a pdf file using Lyx's Export-
>PDF(pdflatex).
But when I try Export->PDF(ps2pdf) I get the above error.
I've pinged the classic thesis folks about this but am not sure if it
is a Lyx configuration problem on my end or a problem with the package
so I am posting to this group as well.
Their config file calls hyperref using:
\PassOptionsToPackage{pdftex,hyperfootnotes=false,pdfpagelabels}
{hyperref}
\usepackage{hyperref} % backref linktocpage pagebackref
which I have no idea what this means or if it is ok.
Basically:
1) what does this error mean?
2) how do I set the print option to pdflatex rather than ps2pdf,
perhaps only for some documents?
TIA!

PS. I'm relatively new to Lyx, only started with it last month, and
have only worked with short articles (no problems printing them).

Re: Using sweave/knitr in master and child documents
Thanks Yihui, for testing this on 2.0.4. You comment would mean that I would have to set my libraries and opts() in each child doc; this is manageable, as each chapter (child doc) has its own data sets. Perhaps its time to move my lyx docs to 2.0.4 (from 1.6.10). Cheers. Mateo. On Monday 16 Jul 2012, Yihui Xie wrote: > Yes it can (I just verified knitr under 2.0.4).

Because (La)TeX is a macro language that is miles more difficult to
machine-parse than, say, XML.
This is why the focus is on *generating* (writing/editing) documents that
can be typeset with LaTeX (and/or HTML, Docbook, ...). LyX is *not* a "LaTeX
editor".
Depending on your needs, existing documents and willingness to change
habits, LyX may boost your productivity or be not the tool of your choice.

I don't understand where LyX wants you to paste macros by hand...
> Why not automate that?
This is a task too difficult to be done completely automatically. LyX did
improve and specific suggestions for further improvement are welcome.

The math-macros are really just for math-mode commands. This is why LyX
does not convert preamble definitions to "math-macros" - is just does not
know whether they are math-mode or text-mode (or both). (See your list below
for a mix of math-mode and text-mode commands.)
Also, math-macros are document specific - defining a math-macro in one
document does not make it available in other ones. This is why my
documents include a file of commonly used math macros -- just like I
\input a file with commonly used preamble definitions in my LaTeX
documents.

Yes, there are many non-supported ways to write things in LaTeX.

I do understand your frustration. Please keep in mind that LyX is not an
enterprise solution promising "easy LaTeX for all" but a volunteer effort
to create a document processor that matches the expectations and ideals
of its developers with much input from the users. As such, it may be not
the right tool for you - at least it needs more patience for things that
might seem easy to you but are very complex from the point of a
programmer...

I hope you will come to a more tempered evaluation of the program.
Even if it is not the tool for you, it might be valuable for your
students.

All of these are rather shortcut aliases for text mode. "math-macro" is not
the right thing to emulate them.
I would try to find out whether tex2lyx already can be configured to do a
back-replacement (e.g. \bf -> \textbf) before converting to LyX format or
write a simple search-and replace script to do this in a preprocessing step.
As you are not going to use these commands directly when writing in LyX,
there is no need for supporting the aliases.

These are (as far as I can see) real math macros, hence it may be sensible
to define math-macros for them (if you want a "nice" look in LyX). However,
it is possible to use them "as is" in math i
