To create a PowerPoint presentation from R Markdown, you specify the powerpoint_presentation output format in the YAML metadata of your document. Please note that this output format is only available in rmarkdown >= v1.9, and requires at least Pandoc v2.0.5. You can check the versions of your rmarkdown package and Pandoc with packageVersion('rmarkdown') and rmarkdown::pandoc_version() in R, respectively. The RStudio version 1.1.x ships Pandoc 1.19.2.1, which is not sufficient to generate PowerPoint presentations. You need to either install Pandoc 2.x by yourself if you use RStudio 1.1.x, or install a preview version of RStudio (>= 1.2.633), which has bundled Pandoc 2.x.
The default slide level (i.e., the heading level that defines individual slides) is determined in the same way as in Beamer slides (Section 4.3.2), and you can specify an explicit level via the slide_level option under powerpoint_presentation. You can also start a new slide without a header using a horizontal rule ---.
