set_parent: Specify the parent document of child documents
Description
This function extracts the LaTeX preamble of the parent document to use for
the child document, so that the child document can be compiled as an
individual document.
Usage
set_parent(parent)
Value
The preamble is extracted and stored to be used later when the
complete output is written.
Arguments
parent
Path to the parent document, relative to the current child
document.
Details
When the preamble of the parent document also contains code chunks and inline
R code, they will be evaluated as if they were in this child document. For
examples, when knitr hooks or other options are set in the preamble of
the parent document, it will apply to the child document as well.
