在rgl或scatter3D中将垂直平面添加到三维散点图

我正在使用包

rgl

和

plot3D

在散点图中绘制三维数据。我的数据如下：

install.packages("rgl")
library(rgl)

x <- Kg$GBMVP_SD
y <- Kg$GBMVP_Ret
z <- Kg$Asset_No

K<- as.matrix(Kg$GRN_No)
RF<- as.matrix(Kg$Risk_Free)


  scatter3D(x , y , z , colvar = K,
    pch = 16, cex = 1.5, xlab = "GMVP Standard Deviation", ylab = "GMVP Return",
    zlab = "Total No of Assets in Portfolio", clab = c("Green Asset No"),
    main = "Global Minimum Variance Portfolio(GMVP) Return and Standard Deviation vs No of Green Assets ", ticktype = "detailed",
    colkey = list(length = 0.5, width = 0.5, cex.clab = 0.75))

install.packages（“rgl”）
