将 3d 点添加到现有 3d 散点图时遇到问题 [英] Having problems adding 3d points to existing 3d scatterplot

问题描述

我目前正在尝试为我的项目生成 3d 散点图.正如您在下面看到的，我将物种列子集划分为三个不同的子集以分离出三个物种.我正在设法使用三个数据集之一生成散点图，但是我在从其他两个数据集向现有散点图添加点时遇到问题.是我做错了什么还是遗漏了什么?

I'm currently attempting to generate a 3d scatterplot for my project. As you can see below I've subset the species column into three different subsets to seperate out the three species. I'm managing to generate the scatterplot fine with one of the three data sets but I'm having problems adding points to the existing scatterplot from the other two data sets. Is there something I'm doing wrong or something I'm missing?

代码:WCC <- read.csv("WaterColumnCurrent.csv")鳕鱼 <- 子集(WCC，物种 ==鳕鱼")黑线鳕<-子集(WCC，物种==黑线鳕")Whiting <- subset(WCC, Species == "Whiting")

Code: WCC <- read.csv("WaterColumnCurrent.csv") Cod <- subset(WCC, Species == "Cod") Haddock <- subset(WCC, Species == "Haddock") Whiting <- subset(WCC, Species == "Whiting")

scatterplot3d(Cod$Mid_X, Cod$Mid_Z, Cod$Mid_Y, pch=20)
points3d(Haddock$Mid_X, Haddock$Mid_Z, Haddock$Mid_Y, pch=2)

推荐答案

这里有一些差异的细目分类(在我含糊的评论之后)，还有一些代码.

Here is a little breakdown of the difference (after my vague comment), with some code.

使用 scatterplot3d 库:

Using scatterplot3d library:

spl <- scatterplot3d(WCC$Mid_X, WCC$Mid_Z, WCC$Mid_Y, pch=20, type="n")
spl$points3d(Haddock$Mid_X, Haddock$Mid_Z, Haddock$Mid_Y, pch=2)

或者使用 rgl 库:

Or using the rgl library:

plot3d(WCC$Mid_X, WCC$Mid_Z, WCC$Mid_Y, pch=20, type="n")
points3d(Haddock$Mid_X, Haddock$Mid_Z, Haddock$Mid_Y, pch=2)
