[Bioc-devel] BiocStyle and fonts

[Andrzej Oleś]

Hi Laurent, Martin,

thank you for bringing this up! As pointed out by Martin, currently
the 'helvet' package gets overridden by Sweave, so this setting
affects only the knitr output.

My feeling is that the default font style should be the same
regardless of the engine used. Too keep thing simple, I would suggest
removing from Bioconductor.sty the following line forcing a particular
font:
\RequirePackage{helvet}

It doesn't help in case of Sweave documents anyway, and setting a
different font in knitr (e.g. helvetica) is straightforward and can be
done manually by simply adding \usepackage{helvet} to the vignette
source if desired.

When it comes to font styles, that's of course a matter of taste and I
don't want to start a war here. However, I think the Latex already
provides a decent default sans serif font and there is no particular
need for BiocStyle to override it.

Cheers,
Andrzej
