Question

我已经有了要使用trans3d添加到我的3D绘图中的预测值和置信区间，但是在使用seq我已经尝试过length(z.bin)的线上出现错误，并阅读其他可能的解决方案，但仍然无法正常工作。

Error in seq.default(lowerCI, upperCI, length.out = 25) : 
  'from' must be of length 1

希望您能帮助我修复我的代码。以下是预测值（z.bin），较高CI（UCI）和较低CI（LCI）：

代码（请不要运行点points（）和trans3d（），不包括res2，但是在那里可以向您展示我要用来创建CI条的循环）

    y.bin <- rep(1,25)
    x.bin <- seq(-10,10,length.out = 25)    
 #   points(trans3d(x.bin, y.bin, z.bin, pmat = res2), col = 1, pch = 16)

        for (i in 1:length(z.bin)) {
          lowerCI <- LCI
          upperCI <- UCI
          CI.bar <- seq(lowerCI,upperCI,length.out=25)
         # lines (trans3d(x.bin[i], y.bin[i], z = CI.bar, pmat = res2), col = #1, lwd=2)
        }

Answer 1

看起来您只需要索引LCI和UCI值，否则就将seq函数提供给整个列表：

for (i in 1:length(z.bin)) {
  lowerCI <- LCI[i]
  upperCI <- UCI[i]
  CI.bar <- seq(lowerCI, upperCI, length.out = 25)
  # lines (trans3d(x.bin[i], y.bin[i], z = CI.bar, pmat = res2), col = #1, lwd=2)
}

在3d绘图平面上绘制置信区间的难度
