rmdshot: Take a snapshot of an R Markdown document
Description
This function can handle both static Rmd documents and Rmd documents with
runtime: shiny.
Usage

port = getOption("shiny.port"), envvars = NULL)Arguments
doc
The path to a Rmd document.
file
A vector of names of output files. Should end with .png,
.pdf, or .jpeg. If several screenshots have to be taken and
only one filename is provided, then the function appends the index number
of the screenshot to the file name.
...
Other arguments to pass on to webshot.
delay
Time to wait before taking screenshot, in seconds. Sometimes a
longer delay is needed for all assets to display properly. If NULL (the
default), then it will use 0.2 seconds for static Rmd documents, and 3
seconds for Rmd documents with runtime:shiny.
rmd_args
A list of additional arguments to pass to either
render (for static Rmd documents) or
run (for Rmd documents with runtime:shiny).
port
Port that Shiny will listen on.
envvars
A named character vector or named list of environment
variables and values to set for the Shiny app's R process. These will be
unset after the process exits. This can be used to pass configuration
information to a Shiny app.
