2、调用三维作图



安装maps包

> install.packages("maps")

R脚本一如下：

library(maps)

map("state",interior=FALSE)



R脚本二如下：

library(maps)

map("state", boundary =FALSE,col="red",add=TRUE) #线宽变为红色



R脚本三如下：

library(maps)

map('world',fill=TRUE,col=heat.colors(10)) #地图



3、R实验：社交数据可视化

R脚本一如下：

library(maps)

library(geosphere)

map("state")



通过设置坐标范围使焦点集中在美国周边，并且设置一些有关颜色

R脚本二如下：

library(maps);

library(geosphere);

xlim <-c(-171.738281,-56.601563);

ylim <-c(12.039321,71.856229);

map("world",col="#f2f2f2",fill=TRUE,bg="white",lwd=0.05,xlim=xlim,ylim=ylim);

注意：以上我在脚本后面有时有加“;”有时没有加上。在正规语法情况下是要加上“;”。
