【问题描述】:
我想绘制按 n 分层的 3D 数据 d1。感谢this answer,到目前为止,我使用rgl 实现了以下解决方案,虽然我找不到将情节旋转到最佳视角的方法,但它看起来已经不错了。在这方面更直接的似乎是plotly,可以用鼠标旋转图形。后者也已经有了我需要的颜色和相应的图例。虽然在这两种方式中我都不明白如何保存图形。如何将它编织成我打算做的 rmarkdown。我不依赖特定的包,只想要以下内容:
- 地层
- 带有图例的颜色/纹理阴影
- 可保存,可编织
这是我的尝试,数据如下。
car::some(d1, 5)
# n x y value
# 37 1000 0.0 0.0 0.000000e+00
# 93 2000 0.3 0.2 2.500834e-04
# 101 2000 0.4 0.4 3.201067e-04
# 111 4000 0.0 0.2 2.400160e-05
# 142 4000 0.5 0.3 6.400427e-05
# change levels
levels <- levels(d1$n) # preserve for later
d1$n <- as.factor(as.numeric(d1$n))
# arrayer
arrayIt <- function(x){
# makes array of d1 by x, y, z
d <- sqrt(nrow(x)/length(unique(x[, 1]))) # dim. of matrices
ar <- array(NA, c(d, d, 3)) # init. array
ar[, , 1] <- matrix(x[, 2], d, d) # x
ar[, , 2] <- matrix(x[, 3], d, d) # y
ar[, , 3] <- matrix(x[, 4], d, d) # z
return(ar)
}
# list of 4 arrays for each n
ls1 <- lapply(seq_along(unique(d1[, 1])), function(n) arrayIt(d1[d1[, 1] == n, ]))
# plot
library(rgl)
lapply(seq_along(unique(d1$n)), function(i){
x <- ls1[[i]][,,1]
y <- ls1[[i]][,,2]
z <- ls1[[i]][,,3]
persp3d(x, y, z, col = i, alpha = .5, add = i > 1) # MARK
})
例如plotly 已经提供了颜色阴影和图例,这非常有用,但是 plot_ly 在上面的 lapply 中不起作用,我也没有找到如何添加层的选项。
library(plotly)
plot_ly(x=x, y=y, z=z, type = "surface") # inserted at MARK didn't work
总之,想要的结果应该是两个图的交集。

不确定为什么轮换对您不起作用。你需要什么输出格式?

这个我没有答案...但是如果你想要 PDF 输出,这很难。查看器不太支持 PDF 中的交互式图形。您可以尝试
rgl::writeASY,但可能会令人失望。
