如何仅在使用 R 的散点图 3d 图中更改点颜色？答案

【问题标题】：How to change point color only in scatter 3d plot using R?如何仅在使用 R 的散点图 3d 图中更改点颜色？

【问题描述】：

我尝试使用 R 将 scatter3d 图中的点颜色更改为黑色，但失败了。点的颜色和面的颜色重叠，查看数据比较困难。

我能得到一些想法吗？

# scatter plot with regression plane
scatter3D(x, y, z, pch = 16, cex = 1,  alpha.col = 0.8, color="black", col = ramp.col(c("dark green", "khaki", "dark red")), bty="b2", 
          theta = 595, phi = 35, ticktype = "detailed", d=200,
          xlab = "", ylab = "", zlab = "",  
          surf = list(x = x.pred, y = y.pred, z = z.pred,  
                      facets=T, border="black"), main = "Room A")

谢谢！

您可以使用points3D 执行您的命令，并包含add=TRUE。

# scatter plot with regression plane
scatter3D(x, y, z,  
          col = ramp.col(c("dark green", "khaki", "dark red")), bty="b2", 
          theta = 595, phi = 35, ticktype = "detailed", d=200,
          xlab = "", ylab = "", zlab = "",  
          surf = list(x = x.pred, y = y.pred, z = z.pred,  
                      facets=T, border="black"), main = "Room A")

points3D(x, y, z, pch = 16, color="black", alpha = 0.8, add=TRUE)
