Read the YAML metadata (and any common output YAML file) for the
document and return an output format object that can be
passed to the render function.
resolve_output_format(
input,
output_format = NULL,
output_options = NULL,
output_yaml = NULL
)An R Markdown output format definition that can be passed to
render.
Input file (Rmd or plain markdown)
Name of output format (or NULL to use
the default format for the input file).
List of output options that should override the options specified in metadata.
Paths to YAML files specifying output formats and their
configurations. The first existing one is used. If none are found, then
the function searches YAML files specified to the output_yaml top-level
parameter in the YAML front matter, _output.yml or _output.yaml, and then uses
the first existing one.
This function is useful for front-end tools that need to modify the default behavior of an output format.
