library(maptools);
x=readShapePoly('bou2_4p.shp')
plot(x);

请教   
在运行代码的时候出现warnings

> provcol=c
> ("red","green","yellow","green","red","green","yellow","blue","red","green","yellow","blue","red","green
错误: 意外的','在"("red","里
> ","yellow","purple","red","green","yellow","purple","red","green","yellow","blue","red","green","yellow",
错误: 意外的符号在"","yellow"里
> "purple","red","green","yellow","purple","blue","green","yellow","purple","green");
错误: 意外的','在""purple","里
> plot(x,col=getColor(x,provname,provcol,"white"),border = "green",xlab="",ylab="")
警告多于50个(用warnings()来显示第一个到第50个)
>
> legend("topleft", legend = provname, bty = "n", col = provcol, pch = 15,ncol = 1, cex = 0.7, lwd = 1)

county_bd$NAME，不是小写name?

我用excel查看了dbf文件，确实是大写的NAME

那就怪了，这个方法行的，估计是哪出了问题
