I am trying to create a world map similar to the map in the third answer to this question. However, when I plot the map it looks completely distorted (see image).
Any explanations for this discrepancy? My code is below.
library(ggmap)
##insert google API key between quotations
ggmap::register_google(key = "")
myMap <- get_googlemap(center = c(lon = 0, lat = 0), zoom = 1, maptype = 'roadmap', size = c(512,396), scale = 2)
# plot map
ggmap(myMap)
