ggplot2 - Incorrect Long/Lat Plotting with ggplot -

i tried make map on ggplot, longitudes , latitudes off. i'm not entirely sure what's going on. example, why lat. going on 100 on map?

you mixed longitude , latitude. if added labels points you'd see none of countries plotted @ correct place.

so make sure x = longitude , y = latitude , it'll work:

ggplot() +    geom_polygon(dat = mdat, aes(long, lat, group = group), fill = "grey50") +   geom_point(data = top_ten_pcapita,               aes(x = long, y = lat, size = refugees_1000_inhabitants), col = "red")
