You can define how and when to rebuild files (such as R Markdown files) using
Make rules, e.g. a rule _posts/%.md: _source/%.Rmd with a command
to build .Rmd to .md will be executed if and only if
foo.Rmd is newer than foo.md. The exit status of the command
make -q will decide whether to rebuild files: rebuilding occurs
only when the exit code is not 0. When an HTML file has been rebuilt,
it will be automatically refreshed in the web browser.
make(dir = ".", ...)The root directory to serve.
Server configurations passed to server_config().
You must have installed GNU Make to use this function. This is normally not a problem for Linux and OS X users (it should be available by default). For Windows users, you can either install GNU Make, or just install Rtools, which also contains GNU Make.
# some built-in examples (if you are not familiar with make, you can take a
# look at the Makefile of each example)
