R：自定义散点图

Question

我正在使用 R 编程语言。我正在尝试按照之前的 Whosebug post () 中的答案 posted 并向散点图添加一个“平面”。

假设我有以下数据：

my_data <- data.frame(read.table(header=TRUE,
row.names = 1,
text="
                         weight   height age
                      1  2998.958 15.26611  53
                      2  3002.208 18.08711  52
                      3  3008.171 16.70896  49
                      4  3002.374 17.37032  55
                      5  3000.658 18.04860  50
                      6  3002.688 17.24797  45
                      7  3004.923 16.45360  47
                      8  2987.264 16.71712  47
                      9  3011.332 17.76626  50
                      10 2983.783 18.10337  42
                      11 3007.167 18.18355  50
                      12 3007.049 18.11375  53
                      13 3002.656 15.49990  42
                      14 2986.710 16.73089  47
                      15 2998.286 17.12075  52
"))

我修改了代码以适合我的示例：

library(scatterplot3d)

model_1 <- lm(age ~ weight + height, data = my_data)

# scatterplot
s3d <- scatterplot3d(my_data$height, my_data$weight, my_data$age, pch = 19, type = "p", color = "darkgrey",
                     main = "Regression Plane", grid = TRUE, box = FALSE,  
                     mar = c(2.5, 2.5, 2, 1.5), angle = 55)

# regression plane
s3d$plane3d(model_1, draw_polygon = TRUE, draw_lines = TRUE, 
            polygon_args = list(col = rgb(.1, .2, .7, .5)))

# overlay positive residuals
wh <- resid(model_1) > 0
s3d$points3d(my_data$height, my_data$weight, my_data$age, pch = 19)

问题：但是，“平面”似乎不存在：

期望的结果：

有人可以告诉我我做错了什么吗？

谢谢

Answer 1

height 和 weight 的顺序导致了问题。

s3d <- scatterplot3d(my_data$weight, my_data$height,my_data$age, pch = 19, type = c("p"), color = "darkgrey",
                     main = "Regression Plane", grid = TRUE, box = FALSE,  
                     mar = c(2.5, 2.5, 2, 1.5), angle = 55)



# regression plane
s3d$plane3d(model_1, draw_polygon = TRUE, draw_lines = TRUE, 
            polygon_args = list(col = rgb(.1, .2, .7, .5)))

# overlay positive residuals
wh <- resid(model_1) > 0
s3d$points3d(my_data$height, my_data$weight, my_data$age, pch = 19)
