Dear R users, I would like to map with R the following countries (with their names on the map) as follows: the first group in red composed by China, Bangladesh, Eypt, Indonesia, South Korea, Nigeria. The second group in blue composed by Brazil, Pakistan, Philippines, Vietnam. The third group in green solely composed by South Africa. Finally, the fourth group in orange composed by India, Mexico and Turkey. I'd also like a legend that assigns the different colors to the various group. I tried several times with library maps but it seems that I failed to find the real setting of xlim and ylim. Can you please help me, I will be very grateful. Best regards George [[alternative HTML version deleted]]
Hi George,
This example is obviously a mess, but it shows the basic elements. The
labels may be placed manually using something like boxed.labels
(plotrix) with lines connecting the labels to the smaller countries.
If you want the labels within the countries you will have to use a big
graphics device.
library(maps)
map("world")
countries=c("China","Bangladesh","Egypt","Indonesia","South
Korea","Nigeria",
"Brazil","Pakistan","Philippines","Vietnam","South
Africa",
"India","Mexico","Turkey")
countrycol<-c(rep("red",6),rep("blue",4),"green",rep("orange",3))
for(i in 1:length(countries)) {
mapinf<-map(region=countries[i],col=countrycol[i],add=TRUE)
xpos<-sum(mapinf$range[1:2])/2
ypos<-sum(mapinf$range[3:4])/2
text(xpos,ypos,countries[i])
}
