Usage

check_yaml(state, error_msg = NULL, append = TRUE)

Arguments

state	the state to start from. This state should be produced by check_rmd.
error_msg	If specified, this overrides the automatically generated message in case the YAML header couldn't be parsed.
append	Whether or not to append the feedback to feedback built in previous states.

Value

A state that zooms in on the YAML header options.
