Details
This routine applies heuristics in order to scan a document for possible resource references. In R Markdown documents, it looks for references to files implicitly referenced in Markdown (e.g.), in the document's
YAML header, in raw HTML chunks, and as quoted strings in R code chunks
(e.g. read.csv("data.csv")).
Resources specified explicitly in the YAML header for R Markdown documents
are also returned. To specify resources in YAML, use the
resource_files key:
---
title: My Document
author: My Name
resource_files:
- data/mydata.csv
- images/figure.png
--- Each item in the resource_files list can refer to:
- A single file, such as
images/figure.png, or - A directory, such as
resources/data, in which case all of the directory's content will be recursively included, or - A wildcard pattern, such as
data/*.csv, in which case all of the files matching the pattern will be included. No recursion is done in this case.
