Serve package vignettes under the vignettes/ directory. Because the
HTML output files should not be included in the source package, this function
renders R Markdown/HTML vignettes, displays them in the web browser, and
deletes the HTML output files. You will see the HTML output when you click
the links on the .Rmd or .Rhtml files (unlike the static HTTP
server, the compiled output instead of the source document is displayed).
vign(dir = ".", ...)The root directory to serve.
Server configurations passed to server_config().
When developing R packages, you may want to preview your vignettes once in a
while. You can certainly click the button in RStudio to do it, but that
requires you to install the package and rebuild the vignettes. With this
function, your vignette will be rebuilt automatically when you update the
source document. Moreover, because the compilation takes place in the current
R session, you can take advantage of devtools::load_all() (which has a
keyboard shortcut in the RStudio IDE) to reload your package and see the
updated vignette in the web browser.
