What are the advantages of using R markdown over R script?
R Markdown has two advantages that are of interest to a researcher. The first is it allows the results of R code to be directly inserted into formatted documents. The second advantage is it is incredibly easy to use.
What is an R script?
An R script is simply a text file containing (almost) the same commands that you would enter on the command line of R. ( almost) refers to the fact that if you are using sink() to send the output to a file, you will have to enclose some commands in print() to get the same output as on the command line.
What is the difference between Markdown and R markdown?

- create documentation for your R package.
- build an interactive dashboard.
- document your analysis like a science lab notebook.
- build a wiki.
How to convert your Markdown files to are scripts?
The most well known way is to use “literate programming”, where the writing and the code are intermingled an .Rmdfile. This is the style of file you get when you create a new “R Markdown” file inside RStudio. There’s another way of mixing code and writing inside a script, and it’s essentially the inverse of an .Rmdfile.
What’s the difference between R Markdown and your notebook?
For example, if an R Notebook .Rmd file is opened, but no code chunks are run, then the HTML file will render all the markdown and input code just fine, but no output will appear. Or, suppose you define some variable x in the Console, but not in a code chunk. If you try to use x somewhere in an R Notebook, it will work just fine.
Can a script be written inside a markdown file?
There’s another way of mixing code and writing inside a script, and it’s essentially the inverse of an .Rmd file. In an R Markdown file, text is considered to be writing unless you wrap it in decoration, by adding backticks around inline code or by putting code in a “code chunk”:
When to use R code in knitr and your Markdown?
For scientific projects we often using knitr and R markdown in RStudio to share results and code either in HTML or PDF format. These are great tools for reproducible research. We find, however, that keeping all of our R code in an R markdown (.Rmd) file creates two problems.
