how to make bullets appear incrementally r presentation

Question

How does one make an R presentation display bullets incrementally. By "R presentation" I mean Rstudio's .rpres -I know this can be done in ioslides, beamer, slidify, etc. but I cannot find any documentation about how this is implemented in .rpres. Is this possible without css? Thanks.
