R markdown: problems with Latex headers

When I setup a header by using a custom .sty file and the fancyhdr package, the header text is automatically formatted and the text is taken from the first header defined in the .Rmd file, and I cannot override this behavior. For instance, I have the following R markdown file

in_header: report.sty
keep_tex: yes
geometry: tmargin=2cm, bmargin=2.5cm
classoption: a4paper


# Behavioural profile of your dog

blah... blah...

```{r echo}

# Some R code here...


And this is the .sty file:

% This file must be saved with UTF-8 encoding, otherwise pandoc will complain
% for instance about nordic characters.

\renewcommand{\familydefault}{\sfdefault} % sans serif
\usepackage{eso-pic, rotating, graphicx, calc}

% Code to add a vertical gray band in the inner margin :
\setlength{\distance}{0.0in} % 0.5in
\setlength{\rulethickness}{0.3in} % 1pt
\setlength{\ruleheight}{11in} % Longueur de la ligne

\chead{I want this header}
Here is some footer text.}

But this is the output:

As you can see, the "THIS IS SOME HEADER" appears as part of the header in capital letters, italics and aligned to the right. How can avoid this?

Thanks in advance!

Answer Source

After loading fancyhdr in report.sty, clear all the headers/footers first using \fancyhf{}. That is,

\fancyhf{}% Clear header/footer
\renewcommand{\headrulewidth}{0.4pt}% Header rule
\renewcommand{\footrulewidth}{0.4pt}% Footer rule
\chead{I want this header}% Centre header
\lfoot{\scriptsize Here is some footer text.}% Left footer

You've only set \chead and \lfoot, so the other four components of the header/footer (three for each: left, centre, right) may still contain content specifications... whatever they may be. \fancyhf{} clears all of these so you can set them as needed.

Of course, if you only want to clear the right header, you can also execute \rhead{}.
