Rmarkdown Presentations - 1

In order to create a Rmarkdown presentation, we click File and then find New File and then R markdown … There are four options:

• Html (ioslides)

This format allows us to create a slide show and the slides could be broken up into sections by using the heading tags # and ##. If a header is not needed, a new slide could be created using a horizontal rule (- - -).

• Html (Slidy)

Similar to ioslides, this format allows to create a slide show broken up into sections by using the heading tag ##. If a header is not needed, a new slide could be created using a horizontal rule (- - -). A Slidy presentation gives a table of content while An ioslides presentation doesn’t.

• PDF (beamer)

This format allows to create a beamer presenation (LaTex). The slides could be broken up into sections by using the heading tags # and ##. If a header is not needed, a new slide could be created using a horizontal rule (- - -).

• PowerPoint

To render an R Markdown document into its final output format, we can click the Knit button to render the document in RStudio and RStudio will show a preview of it.
