Bookdown allows for a table of contents, list of figures, list of tables, and preface. When using the first three and generating a PDF, the heading correctly reflects "Contents", "List of Figures", or "List of Tables". However, with an unnumbered preface one would expect to see "Preface" added to the heading but it does not appear and instead the last heading persists, so the preface, even if spanning multiple pages, will have the header "Contents", for example.
If I take the minimal book example found at https://github.com/rstudio/bookdown-demo and add # Preface {-} in index.Rmd I also have to manually add the following to get the desired behaviour:
# Preface {-}
\renewcommand{\chaptermark}[1]{\markboth{\uppercase{#1}}{\uppercase{#1}}}
\chaptermark{Preface}
Blah blah blah
\renewcommand{\chaptermark}[1]{\markboth{\uppercase{\thechapter. \ #1}}{}}
i.e., in order to get "Preface" to appear in the headings and then for the remaining headings to alternate section and chapter titles.
I suspect this is a glitch but before reporting this to the author of bookdown he asks that this first be posed here, so any insight would be most welcome.
