Maps not showing in the RStudio Viewer when using plotly in R

I've made a map using ggplot2 in R. I am now trying to use plotly so that I can make it more interactive (and in particular use tooltips). However, anything I try ends up with me just getting a blank viewer panel in RStudio. I am able to view other things with plotly (for e.g. a basic line chart), but not maps.

For the sake of being reproducible, I am also trying using this basic map taking code from here. 

library(ggplot2)
library(plotly)

usa <- map_data("usa")
states <- map_data("state")

usa_map <- ggplot(data = states) + 
  geom_polygon(aes(x = long, y = lat, fill = region, group = group), color = "white") + 
  coord_fixed(1.3) +
  guides(fill=FALSE)

This plots me a map, just how I want it.

Next, so far I have tried this:

ggplotly(usa_map)

And this:

usa_map_view <- plotly_build(usa_map)
usa_map_view

But both of these just give me the blank screen, without any error messages.

Any ideas where I'm going wrong?

Solution

  • Yes. As Stephane Laurent mentioned, it can be viewed in the browser.

    This is what I got in the browser. It has all the states listed on the right(scrollable list). Plot

    You can view in browser by clicking "open in new window" in "viewer".
