smartmap is an R package for previewing spatial data
as leaflet maps. It is
designed for interactive use and produces nice maps with minimal typing
required. In contrast to other similar packages, smartmap does not
require an sf or sp object as input, but
just works with normal data.frames or
matrices that have longitude and latitude columns. See the package homepage for
more infos.
You can install smartmap from CRAN:
install.packages("smartmap")or get the development version from GitHub with:
# install.packages("remotes")
remotes::install_github("s-fleck/smartmap")smartmap is in maintenance mode since I don’t much work with spatial data anymore, so new features are unlikely to be added.
library(smartmap)
# coordinate pairs without names are interpreted as longitude/latitude
smap(c(16.422524, 48.185686))
# if you supply column names, smap uses those to identify the correct columns
smap(c(LAT = 48.185686, LoNgItuDE = 16.422524))
# when supplied with an url or file system path, smap tries its best to discover
# supported spatial datasets
# Note: the naturalearthdata url doesn't work anymore and i didn't find another good new example
# smap("https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/cultural/ne_50m_admin_0_countries.zip")
# You can call smap() on existing leaflet objects to add background tiles and
# a ruler for measuring distance
library(leaflet)
lf <- leaflet::leaflet() %>%
leaflet::addCircleMarkers(lng = 16.422524, lat = 48.185686)
