smartmap is a package for previewing spatial data as
leaflet maps in R. It is designed primarily for interactive use and
produces nice maps with minimal setup 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 function reference
for more info.
And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("s-fleck/smartmap")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
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)
