Day 19 of 30DayMapChallenge: « 5-minute map » (previously).
Setup
library(tidyverse) library(leaflet) library(httr) library(fs) library(glue)
Data
We reuse the Geonames data from Bad map.
gn_file <- "~/data/geonames/allCountries.zip"
if (!file_exists(gn_file)) {
GET("http://download.geonames.org/export/dump/allCountries.zip",
write_disk(gn_file))
}
gn <- read_delim(
gn_file,
delim = "\t",
col_names = c("geonameid",
"name",
"asciiname",
"alternatenames",
"latitude",
"longitude",
"feature_class",
"feature_code",
"country_code",
"cc2",
"admin1_code",
"admin2_code",
"admin3_code",
"admin4_code",
"population",
"elevation",
"dem",
"timezone",
"modification_date"))
We randomly keep five places containing “minute”…
set.seed(314) minute <- gn |> filter(str_detect(asciiname, "\\b[Mm]inute\\b")) |> slice_sample(n = 5)
Map
minute |>
leaflet() |>
addCircleMarkers(popup = ~ glue("{name} ({asciiname})<br />
<b>{country_code}</b>"),
label = ~ asciiname,
labelOptions = labelOptions(noHide = TRUE)) |>
addTiles(attribution = "Geonames and © OpenStreetMap, ODbL")
