Specify the parent document of child documents
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.
set_parent(parent)
parent |
Path to the parent document, relative to the current child document. |
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.
The preamble is extracted and stored to be used later when the complete output is written.
Obviously this function is only useful when the output format is LaTeX.
This function only works when the child document is compiled in a
standalone mode using knit() (instead of being called in
knit_child()); when the parent document is compiled, this
function in the child document will be ignored.
## can use, e.g. \Sexpr{set_parent('parent_doc.Rnw')} or
# <<setup-child, include=FALSE>>=
# set_parent('parent_doc.Rnw')
