Rwireframe（）使用格子错误的颜色条

Question

我尝试绘制样使用wireframe()与lattice

彩条错误

  require(marmap)
  require(lattice) 

     Bathy2 <- getNOAA.bathy(lon1 = 30, lon2 = 47,
                               lat1 = -12, lat2 = -28, resolution = 2)
#plot of the area + transect
     plot(Bathy2, image=TRUE, land = TRUE, lwd = 0.03,
             bpal = list(c(0,max(Bathy2), greys), c(min(Bathy2), 0, blues)))
     belt3 <- get.box(Bathy2, x1 = 34, x2 = 46, y1 = -20, y2 =  -20, width = 3, col = "red")

#3Dplot of the transect
       wireframe(belt3, shade = T, zoom = 1.1,
                  aspect = c(1/4, 0.1),
                  screen = list(z = -60, x = -55),
                  par.settings = list(axis.line = list(col = "white")),
                  par.box = c(col =rgb(0, 0, 0, 0.1)),
                  xlab="", colorkey = TRUE)

我得到的是粉红色的彩条

Answer 1

如此处所述 ，使用shade = TRUE ：

根据小平面相对于观察方向和光源的方向，相同的Z值可能具有不同的颜色。 因此，色键不起作用。

所以我建议改用drape = TRUE ：

# 3Dplot of the transect
wireframe(belt3, drape = TRUE, zoom = 1.1,
          aspect = c(1/4, 0.1),
          screen = list(z = -60, x = -55),
          par.settings = list(axis.line = list(col = "white")),
          par.box = c(col =rgb(0, 0, 0, 0.1)),
          xlab="", colorkey = TRUE, lwd = 0.2)

您也可以定义自己的调色板。 只需检查?wireframe 。
