您可以使用leaflet并在OpenStreetMap层上绘制点。使用此软件包，您不需要API或链接帐户。

# Packages
library(dplyr) # to use the pipe operator (magrittr can be used too)
library(leaflet) # acces to openstreetmap layer
library(htmltools) # label each point
# Data
data <-  structure(list(
Univ.location = c( "Uppsala University  Uppsala",
"Dalarna University Borlänge", "University of Skövde   Skövde", 
"University of Skövde   Skövde", "University of Technology    Luleå", 
"Uppsala University  Uppsala"),
lon = c(17.63893, 15.43397, 13.84612, 
13.84612, 22.1567, 17.63893),
lat = c(59.85856, 60.4843, 58.39028, 
58.39028, 65.58482, 59.85856)),
class = "data.frame", row.names = c(NA, -6L))
# Map

data %>% 
leaflet() %>% 
addTiles() %>% 
addCircleMarkers( label = ~htmlEscape(Univ.location))
