spin_child
(Package: knitr) :
Spin a child R script
This function is similar to knit_child() but is used in R scripts instead. When the main R script is not called via spin(), this function simply executes the child script via sys.source(), otherwise it calls spin() to spin the child script into a source document, and uses knit_child() to compile it. You can call this function in R code, or using the syntax of inline R expressions in spin() (e.g. {{knitr::spin_child('script.R')}}).

set_alias
(Package: knitr) :

asis_output
(Package: knitr) :
Mark an R object with a special class

include_url
(Package: knitr) :
