[R] Zoom In/Out maps library

Thank you - that's helpful.  Going to have to read up on sf and mapview
library. Those are new ones.  Then to add a point feature layer (lat/long)
where would I insert that?

Library(maps)
Library(sf) # simple features
Library(mapview)

world.map <- maps::map("world", plot = FALSE, fill = TRUE) 
p <- sf::st_as_sf(world.map, coords = c('x', 'y')) 
mapview::mapview(p, legend=FALSE)
