在 scatterplot3d 中划分颜色

Question

根据Year 类别需要您的建议来为 scatterplot3d 着色。我的数据集如下：

data2d

No d_Mart     d_Train   Price  Year
1  371.20750  945.8907  304    2013
2  1396.94337 2347.5052 446    2015
3  393.82319  1092.1655 802    2016
4  1183.18903 1455.1527 445    2017
5  374.89814  1027.8457 707    2018
6  260.44635  871.1573  310    2019
7  366.81782  1258.1917 534    2014

我创建的语法如下

scatterplot3d(data2d[,1:3], pch = 20, type="h",
              main="Distance to market vs distance to train station",
              xlab = "Distance to market",
              ylab = "Distance to train station",
              zlab = "Price (IDR)",
              angle = 45,
              color = 'red',
              legend = levels(data2d$Price),
              )

结果，

我无法按年份划分颜色

你能帮我从数据集中根据年份划分颜色吗？

Answer 1

您可以将data2d$Year 传递给color：

scatterplot3d(data2d[,1:3], pch = 20, type="h",
              main="Distance to market vs distance to train station",
              xlab = "Distance to market",
              ylab = "Distance to train station",
              zlab = "Price (IDR)",
              angle = 45,
              color = data2d$Year,
              legend = levels(data2d$Price),
              )
