knitr :: spin防止所有块被执行

Question

I'd like to document some R functions (not scripts) as html pages using spin(). I thought of something like:

#' Test of rmarkdown  wit spin() for an html documented function
#' =======================================================
#+ eval=FALSE
test <- function(x,y)
{
  #' comment 1
  z <- x + y 
  #' comment 2
  z
}

But the #+ eval=FALSE applies to the first chunk only. Is there a way to prevent the actual execution of all chunks with on single command at the beginning?

Answer 1

Set it globally:

#' Test of rmarkdown  wit spin() for an html documented function
#' =======================================================
#+ setup, include=FALSE
knitr::opts_chunk$set(eval = FALSE)
#+
test <- function(x,y) {
  # comment 1
  z <- x + y
  # comment 2
  z
}
