Why does the ggplotly function not display in my Rmarkdown ioslides

Question

I am trying to make a slide with an interactive graph on it. The ggplotly function works in the console but does not show in the markdown chunk - the corresponding slide is blank. A normal plot shows up just fine.

library(plotly)
df = data.frame(a = c(1:3,1:10))

ggplotly(p)

Fixed by opening directly into browser from .html file and not via RStudio
