Subject: [Rd] UTF8 markdown vignette
Message-ID: <AA818EAD2576BC488B4F623941DA7427F3C7D1D8@inbomail.inbo.be>

Dear all,

I'm trying to use a Markdown vignette with UTF-8 encoding. It compiles well when knitting the vignette in RStudio, but it fails to recognize the UTF-8 settings when building the source package. Can someone point out what I'm doing wrong? I tried to put the relevant information below.

Best regards,

Thierry

Details:

Using 64-bit R 3.1.2 with encoding = "native.enc" on Windows 7 with Rstudio 0.97.1091.

The source packages is build using the devtools package. The build command is R --vanilla CMD build  "myPackage" --no-manual  --no-resave-data

The DESCRIPTION file has

VignetteBuilder: knitr
Suggests: knitr
Imports: rmarkdown

The markdown vignette YAML contains
vignette: >
  %\VignetteEngine{knitr::rmarkdown}
  %\VignetteIndexEntry{The title}
  \usepackage[utf8]{inputenc}

The custom output style converts the markdown to beamer with the --latex-engine = xelatex flag.

The vignette in tar.gz passes R --vanilla CMD check  --timings --as-cran

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
