Some R Examples [R table and Graphics]

Advanced Data Visualization in R (Some Examples)

Example: > library(ggmap) > map1 = suppressMessages(get_map( + location = 'Istanbul', zoom = 14, #zoom-in level + maptype="satellite")) #map type > ggmap(map1) >

 

 

Example:

> library(ggmap)

> map = suppressMessages(get_map(location = 'Turkey', zoom = 4)) > ggmap(map)

Example:

trk = suppressMessages(geocode(c( + "Erzurum, Turkey", + "Istanbul,Turkey", + "Izmir,Turkey",

+ "Bursa,Turkey"), source="google")) > ggmap(map) + geom_point(aes(x=trk$lon, y = trk$lat), + lwd = 4, colour = "red") + ggtitle("Ziyaret ettiğim iller")
