Can anyone tell me how to enumerate \subsections? For example:

\subsection{Double-space a file.}
\subsection{Triple-space a file.}

I want this to look like:

1.1 Double-space a file.
1.2 Triple-space a file.

At the moment I only get this:

Double-space a file.
Triple-space a file.

This is unexpected behavior for the default setting. Perhaps you included something at the preamble that you didn't show. Minimal working example (see meta.tex.stackexchange.com/questions/228/…) will be very helpful. – ipavlic Apr 29 '11 at 11:56
ipavlic, what do you mean it's unexpected behavior? I think you misunderstood the question - I want the subsections to be numbered. That's all. – Peteris Krumins Apr 29 '11 at 12:07
If you just compile a minimal document like \documentclass{article} \begin{document} \section{Section} \subsection{Subsection} \end{document} your output will look like this 1 Section 1.1 Subsection. Therefore, you have included something to your document that changed the default behavior. Had you included a MWE you would have most likely found the culprit yourself, or would have made it possible for us to try help you better. – ipavlic Apr 29 '11 at 12:24

You can set the level until which (sub)sections are numbered by setting the counter secnumdepth. \setcounter{secnumdepth}{whatever}

I just tried this but it didn't change the result, I still get unnumbered subsections. I did: \setcounter{subsection}{1}. – Peteris Krumins Apr 29 '11 at 12:12
I am writing a \documentclass{memoir} btw. – Peteris Krumins Apr 29 '11 at 12:14
@Peteris: I think you misunderstand the answer. You should change the value of secnumdepth (to 2 or larger), not subsection. – Leo Liu Apr 29 '11 at 12:18
@Raphink memoir provides its own methods for changing sections; although titlesec can be used with memoir, it's preferable not to. – Alan Munn Apr 29 '11 at 12:32
@Raphink memoir incorporates a lot of packages within the class directly: abstract, appendix, array, booktabs, ccaption, chngcntr, crop, dcolumn, delarray, enumerate, epigraph, ifmtarg, ifpdf, index, makeidx, moreverb, needspace, newfile, nextpage, pagenote, patchcmd, parskip, setspace, shortvrb, showidx, tabularx, titleref, tocbibind, tocloft, verbatim so you should be careful recommending packages to memoir users. – Alan Munn Apr 29 '11 at 12:40

For memoir class the easier syntax is \setsecnumdepth{argument} (section 6.3 in the manual). In your case you would use


In case you want the Table Of Contents, to show up to subsections use


The argument of maxtocdepth can be different than setsecnumdepth. I think that this is the most usual case.
