R语言 三维画图

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

#三维绘图

install.packages("scatterplot3d")  #安装包

library(scatterplot3d)

#散点图是描述二元变量关系的图，如果需要一次性对三个变量交互关系进行可视化，可使用三维图

#scatterplot3d(x,y,z),x绘制在横轴上，y绘制在竖轴上，z绘制在透视轴上

z=seq(-10,10,0.01)

x=cos(z)

y=sin(z)

scatterplot3d(x,y,z,highlight.3d = TRUE)

#scatterplot3d只能画静态三维图，如果需要交互旋转对三维图，可采用rgl包

install.packages("rgl") #安装包

library(rgl)   #加载包

attach(iris)   #**iris数据集，使之成为当前数据集

head(iris)   #数据前六行

library(rgl)

a=Species

levels(a)=c("Green","Red","Blue")  #为不同种类对花画不同颜色

plot3d(Sepal.Length,Sepal.Width,Petal.Length,col=a,size=10)#可以拖动旋转对图
