[R-sig-Geo] Fwd: Pie charts on a map. v2

[Baldwin, Jim -FS]

I now see the issue:  you have lat and long reversed in pie.chart.txt.  That puts you in Somolia and Kenya (which is why I suggested mapRegion="Somalia" earlier).

​Thank you so much for answering! I have checked the two points that you have mentioned. I actually had library(rworldxtra) in my original, longer code, so I have copied it to this shorter one. However, R still refuses to plot anything on the map.

About point 2, I am focusing on the Catalan coast with
xlim=c(.5,3.5),ylim=c(40.5,42.42)

​and it seems that there is no option for "NE Spain", "Catalonia" or anything of the kind.

I enclose the modified code herein.

Best regards,

Jue​

I think there are two issues:

1. You need the rworldxtra package to get the countriesHigh dataset so adding in
    library(rworldxtra) is necessary.
2. I think you need to "focus" the figure to a smaller area and add in a statement
    like mapRegion="Somalia" in the mapPies function.

Dear sirs/madams,

May someone please help me with this issue: I have been trying to plot pie charts on a map, without much success (see code enclosed herein). This is quite distressing to me, as I had plot the same kind of map before without problems. It would be appreciated if anyone would point out the flaw. I enclose a reproducible set of data and codes for you to work with. I have tested the code, you just have to paste the three of the files in the same folder.

Thank you very much in advance.
