The file extension is <code>*.Rhtml</code>, and it has to include a special comment to tell R that this file needs to be compiled by <strong>knitr</strong>:</p> <pre><!-- %\VignetteEngine{knitr::knitr} %\VignetteIndexEntry{The Title of Your Vignette} --> </pre> <p>Now you can write R code chunks:</p> <!--begin.rcode cars-demo summary(cars) fit=lm(dist~speed, data=cars) summary(fit) end.rcode--> <p>You can also embed plots, for example:</p> <!--begin.rcode cars-plot, fig.width=7, fig.height=6, fig.align='center' par(mar=c(4,4,.1,.1)) plot(cars, pch=19) end.rcode--> <p>For package vignettes, you need to encode images in base64 strings using the <code>knitr::image_uri()</code> function so that the image files are no longer needed after the vignette is compiled. For example, you can add this chunk in the beginning of a vignette:</p> <!--begin.rcode setup, eval=FALSE end.rcode--> </body> </html>
