knitr (version 1.46)

knit_child: Knit a child document

Description

This function knits a child document and returns a character string to input the result into the main document. It is designed to be used in the chunk option child and serves as the alternative to the SweaveInput command in Sweave.

Usage

knit_child(..., options = NULL, envir = knit_global())

Value

A character string of the content of the compiled child document is returned as a character string so it can be written back to the parent document directly.

Arguments

...

Arguments passed to knit.

options

A list of chunk options to be used as global options inside the child document. When one uses the child option in a parent chunk, the chunk options of the parent chunk will be passed to the options argument here. Ignored if not a list.

envir

Environment in which code chunks are to be evaluated, for example, parent.frame(), new.env(), or globalenv()).
