Partial / incremental slides

For pdf, png, gif, mp4, and pptx output types, if you want to render a new slide for each increment on incremental slides, set partial_slides = TRUE in any of the following render functions:

to_pdf()
to_png()
to_gif()
to_mp4()
to_pptx()

--

For example, the following code would render this slide as two slides in a pdf instead of one:

to_pdf("slides.Rmd", partial_slides = TRUE)
to_pdf("slides.html", partial_slides = TRUE)

Note: This option requires the chromote and pdftools packages.

Complex slides

"Complex" slides are slides that contain panelsets (like the one on this slide) or other html widgets / advanced features that might not render well as a pdf. To render these on separate slides, set complex_slides = TRUE in to_pdf(), to_png(), to_gif(), to_mp4(), or to_pptx().

.panelset[ .panel[.panel-name[Chunk]

head(mtcars)

]

.panel[.panel-name[Output]

head(mtcars)

] ]

Use the `slides` argument to control which slides get built

Examples rendering from PDF to PNG:

# Render the first or last slide only
to_png(from = "slides.pdf", to = "first_slide.png", slides = "first")
to_png(from = "slides.pdf", to = "last_slide.png", slides = "last")

# Choose subsets of slides
to_png(from = "slides.pdf", slides = c(1, 3, 5))
to_png(from = "slides.pdf", slides = -1) # Negative indices remove slides

# Render all slides
to_png(from = "slides.pdf", slides = "all")
