Create markdown headers as normal: #' # for h1, #' ## for h2, etc. For this purpose, you can set the chunk option echo = FALSE to hide the source code instead, so readers will not be distracted by the program code for computing. The function knitr::all_labels() returns a vector of all chunk labels in the document, so ref.label = knitr::all_labels() means retrieving all source code chunks to this code chunk. ```{r cars} YOU CAN WRITE YOUR CODE HERE ``` And the non-highlighted section is where you can write your report.

Most of the time you’ll likely be debugging in straightforward, free-standing R functions and scripts. Alternatively you can set the root.dir chunk using rprojroot: opts_knit$set(root.dir = rprojroot::find_rstudio_root_file()) Some advantages of using R Markdown: R code can be embedded in the report, so it is not necessary to keep the report and R script separately. knit - You can knit the file. Plus, R Markdown can render styling from Cascading Style Sheets (CSS) and Hyper Text Markup Language (HTML), which is what non-R Markdown websites use. The default values for them may not be the appropriate environment: you may end up creating variables in the wrong environment, and being surprised that certain objects are not found in later code chunks. So, Googling what you want to do and trying it in your R Markdown files is a good way to learn. Since ref.label can be a character vector of arbitrary chunk labels, you can certainly filter the labels to decide a subset of code chunks to display in the code appendix.

Notebooks can be compiled to anyoutput format including HTML, PDF, and MS Word. source("your-script.R", local = knitr::knit_global()), # or sys.source("your-script.R", envir = knitr::knit_global()). source(here("functions.R")) source(here("subdirectory", "DataDependency.R")) source(here("subdirectory2", "furtheranalyis.R")) This is probably a better solution as it doesn't rely on knitr options. If your R Markdown document has a large amount of code, you may consider putting some code in external R scripts, and run these scripts via source()or sys.source(), e.g., ```{r, include=FALSE}source("your-script.R", local = knitr::knit_global())# or sys.source("your-script.R", envir = knitr::knit_global())```. You can transform an R Markdown file in two ways. When we open RStudio for the first time, we’ll probably see a layout like this: … For example: rmarkdown::render("analysis.R") rmarkdown::render("analysis.R", "pdf_document") The first call to render creates an HTML document, whereas the second creates a PDF document.
