1d:T755,# First Pre-knitting Processing, then knitr::knit, then rmarkdown::render, then Post HTML-rendering Processing 1) In pre-knitting processing, function takes in a Rmd file, evaluates code chunks which are marked as between adjacent lines of @@@s, and then replace these code chunks with evaluated output captured using capture.output function. 2) Function then calls knitr::knit followed by rmarkdown::render. 3) After which, in post HTML-rendering processing, function evaluates code chunks in between ` captured using capture.output function. Typically, we want to insert an external HTML file and we can use ` This function will read in the external html file and replace this ` contents in the html file. ```r preknit_knit_render_postrender(pRmdfile, outhtml = NULL) ``` ## Arguments - `pRmdfile`: - input Rmd file - `outhtml`: - output html file ## Returns The output html file will have the codes between @@@ and/or \`%%% \` (where \` is a backtick) code chunks evaluated ## Examples ```r oldwd <- getwd() setwd(tempdir()) #pandoc.exe is required to run this code samplermd <- tempfile('test', getwd(), '.Rmd') addhtml <- 'test__test.html' #generate the test Rmd file writeLines(c('---', 'title: "Example Usage"', 'output: html_document', '---', '', 'This document is used for various similar reports.', '', '@@@', "cat(paste('#Dynamic Header1', rnorm(1)))", '@@@', '', '`%%% writeLines(readLines("test__test.html"))`', '', '@@@', 'cat(paste("##Dynamic Header2", rnorm(1)))', '@@@', '', 'Some content is invariant across different reports.'), samplermd) #generate test html file writeLines(c('
