Unable to duplicate RPubs example

[smach]

I was trying to duplicate your code here

http://rpubs.com/bhaskarvk/electoral-Map-2016

But I keep getting this error message

Error in derivePoints(data, lng, lat, missing(lng), missing(lat), "addMarkers") : 
  addMarkers requires non-NULL longitude/latitude values

I had the same problem when trying to create a tilegram using my own data with the 538 style. Any ideas?

I think it's because of https://github.com/rstudio/leaflet/pull/310. If you git clone rstudio/leaflet and build after merging that PR, that error should go away.

devtools::install_github("rstudio/leaflet#310") should do it, I think.

That did the trick, thanks!

The fix has now been merged in leaflet master.
