R: Copy YAML code to your clipboard or write to a new R Markdown...

use_yml {ymlthis}

R Documentation

Copy YAML code to your clipboard or write to a new R Markdown file

Description

use_yml() takes a yml object and puts the resulting YAML on your clipboard to paste into an R Markdown or YAML file. use_rmarkdown() takes the yml object and writes it to a new R Markdown file. You can add text to include in the body of the file. If it's not specified, use_rmarkdown() will use setup_chunk() by default. You can also set a default for body using options(ymlthis.rmd_body = "{your text}"); see use_rmd_defaults(). Together with specifying default YAML (see use_yml_defaults()), use_rmarkdown() also serves as an ad-hoc way to make R Markdown templates. You may also supply use_rmarkdown() with an existing R Markdown file from which to read the YAML header; the YAML header from the template is then combined with .yml, if it's supplied, and written to a new file. use_index_rmd() is a wrapper around use_rmarkdown() that specifically writes to a file called index.Rmd. By default, use_yml() and use_rmarkdown() use the most recently printed YAML via last_yml().

Usage

use_yml(.yml = last_yml())

use_rmarkdown(
  .yml = last_yml(),
  path,
  template = NULL,
  include_yaml = TRUE,
  include_body = TRUE,
  body = NULL,
  quiet = FALSE,
  open_doc = interactive(),
  overwrite = getOption("usethis.overwrite", FALSE)
)

use_index_rmd(
  .yml = last_yml(),
  path,
  template = NULL,
  include_yaml = TRUE,
  include_body = TRUE,
  body = NULL,
  quiet = FALSE,
  open_doc = interactive()
)

Arguments

`.yml`	a `yml` object created by `yml()`, `as_yml()`, or returned by a `⁠yml_*()⁠` function
`path`	A file path to write R Markdown file to
`template`	An existing R Markdown file to read YAML from
`include_yaml`	Logical. Include the template YAML?
`include_body`	Logical. Include the template body?
`body`	A character vector to use in the body of the R Markdown file. If no template is set, checks `getOption("ymlthis.rmd_body")` (see `use_rmd_defaults()`) and otherwise uses `setup_chunk()`.
`quiet`	Logical. Whether to message about what is happening.
`open_doc`	Logical. Open the document after it's created? By default, this is `TRUE` if it is an interactive session and `FALSE` if not. Also checks that RStudio is available.
`overwrite`	Logical. If `TRUE`, overwrites the file without asking for permission. If `FALSE`, asks interactively if the user wishes to do so. Checks the user's `usethis.overwrite` option if set and is otherwise `FALSE` by default.
