GGMAP : Unable to create points on the map

I am trying to pepare the NYC map using gig-lot, and trying to simply point the lat and longitudes using ggmap.

I can only see the map but no points it was working fine yesterday, the only diirence I did is I sliced the ds 2000 rows instead of whole.

Could you please include your code as a self-contained reprex (short for minimal reproducible example)? It will help us help you if we can be sure we're all working with/looking at the same stuff.

If you've never heard of a reprex before, you might want to start by reading the help page. The reprex dos and don'ts are also useful.

For pointers specific to the community site, check out the reprex FAQ, linked to below.
