R Help
Anyone know if I can add a zoom In/Out function to the maps available via the "maps" library? Or do I need to use a different mapping library?
world.map <- map_data("world")
ggplot(data = world.map) +
geom_polygon(mapping = aes(x=long, y=lat, group=group))

Zoom In/Out maps library
7 messages · reichm@@j m@iii@g oii sbcgiob@i@@et, rmendelss gmail, Roy Mendelssohn - NOAA Federal
world.map <- maps::map("world", plot = FALSE, fill = TRUE)
p <- sf:: st_as_sf(world.map, coords = c('x', 'y'))
map view::map view(p)

Or if you prefer plotly:
world.map <- maps::map("world", plot = FALSE, fill = TRUE)
p <- sf:: st_as_sf(world.map, coords = c('x', 'y'))
plotly::ggplotly(
ggplot2::ggplot(data = p) + ggplot2::geom_sf()
)

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)

see https://r-spatial.github.io/mapview/index.html The main thing is the data types that map view supports, so you must have a raster or an spatial object like an "sf" object. So points would have to also be an sf object and the two combined (sf has commands to do this) or perhaps you can do ti directly in mapview, I haven't played with it much. The plotly example I sent works with ggplot2, so if you know how to build up the map in ggplot2 you can try that, though again as far as I can see plotly for maps needs sf objects. Mainly sent you the links to get you started. I haven't played with either much, just know that they exist and zoom maps. HTH, -Roy

Also, I forgot that tmap can do interactive maps, see: https://geocompr.robinlovelace.net/adv-map.html#interactive-maps -Roy
