att_from_rmd: Get all dependencies from a Rmd file

Description

Get all dependencies from a Rmd file

Usage

att_from_rmd(
  path,
  temp_dir = tempdir(),
  warn = -1,
  encoding = getOption("encoding"),
  inside_rmd = NULL,
  inline = TRUE
)
att_from_qmd(
  path,
  temp_dir = tempdir(),
  warn = -1,
  encoding = getOption("encoding"),
  inside_rmd = NULL,
  inline = TRUE
)

Value

vector of character of packages names found in the Rmd

Arguments

path

Path to a Rmd file

temp_dir

Path to temporary script from purl vignette

warn

-1 for quiet warnings with purl, 0 to see warnings

encoding

Encoding of the input file; always assumed to be UTF-8 (i.e., this argument is effectively ignored).

inside_rmd

Logical or NULL. Whether the function is being called from inside a knit session, in which case the actual purl step must be delegated to an external R process. When NULL (the default), this is auto-detected via knitr::opts_knit$get("out.format").

inline

Logical. Default TRUE. Whether to explore inline code for dependencies.

Examples

dummypackage <- system.file("dummypackage",package = "attachment")
# browseURL(dummypackage)
att_from_rmd(path = file.path(dummypackage,"vignettes/demo.Rmd"))
