RStudio can convert your R Markdown file into an HTML file. This is called “knitting” the file. It is a nice way to visualize the output of your code and text together in a human readable, single document.

Select the “Knit to HTML” option in the “Knit” menu of RStudio. It should produce something that looks like this:

RStudio can also “knit to PDF” and “knit to Word”, feel free to experiment with those if you wish.

Knit to PDF

You can also select the “Knit to PDF” option in the “Knit” menu and you should get a PDF version of your R Markdown document. If you get an error message, try executing the following command in the Console: tinytex::install_tinytex(), and then try to “Knit to PDF” again.
