My problem is that page breaks and horizontal lines are inserted after sections, some chapters and the TOC. I have included all the code since I have no clue about which part of it is causing the problem or why.

\usepackage[letterpaper, top=4cm, bottom=2.5cm, left=4cm, right=2.5cm]{geometry}
\addto\captionsspanish{\renewcommand*\contentsname{TABLA DE CONTENIDOS}}

Lorem  ipsum  dolor  sit  amet,  consectetuer  adipiscing  
elit.   Etiam  lobortisfacilisis sem.  Nullam nec mi et 
neque pharetra sollicitudin.  Praesent imperdietmi nec ante. 
Donec ullamcorper, felis non sodales
\chapter{Reproducible Research}

The lines are to separate the headers of your pages and the text. You can disable them by setting its width to 0:


It gets set by the fancyhdr package. They are by default disabled on "special" pages, like the first page of the TOC or of chapters, which use a different format.

The empty pages are inserted because every chapter should start as a right page. If you want to disable this (which you really shouldn't), use the openany option:


You shouldn't put section without a chapter, because that doesn't make sense (your first section*).

  • Thanks! This solves the problem with horizontal lines, but the page breaks are still there.

  • I've already added that, but please consider if you really want to remove them.
