When using tikzDevice as device when plotting with knitr and rmarkdown, there appear to be differences between using global options and chunk options for setting the PDF engine. I will demonstrate this with a R Markdown document with embedded PDF documents.
Setting engine = "luatex" has no effect when using the dev.args chunk option, the PDF metadata still indicate pdfTeX as creator:
---title: "Setting PDF engine via chunk options"output: html_document---```{r, dev-tikz, dev = "tikz", dev.args = list(engine = "luatex")}
par(mar = c(4, 4, 2, .1))curve(dnorm, -3, 3, xlab = '$x$', ylab = '$\\phi(x)$', main = 'The density function of $N(0, 1)$')text(-1, .2, cex = 3, col = 'blue', '$\\phi(x)=\\frac{1}{\\sqrt{2\\pi}}e^{\\frac{-x^2}{2}}$')```
Only when setting the global option tikzDefaultEngine = "luatex", the metadata indicate LuaTeX as creator:
---title: "Setting PDF engine via global options"output: html_document---```{r}options(tikzDefaultEngine = "luatex")``````{r, dev-tikz, dev = "tikz"}
par(mar = c(4, 4, 2, .1))curve(dnorm, -3, 3, xlab = '$x$', ylab = '$\\phi(x)$', main = 'The density function of $N(0, 1)$')text(-1, .2, cex = 3, col = 'blue', '$\\phi(x)=\\frac{1}{\\sqrt{2\\pi}}e^{\\frac{-x^2}{2}}$')```
