如何在 R 中旋转 3D Plotly，更新？

Question

我想用 3D 表面制作动画情节

我试图复制这个例子

但是我无法让它工作，不旋转

library(shiny)
library(plotly)
library(htmlwidgets)

ui <- fluidPage(
  plotlyOutput("graph")
)

server <- function(input, output, session) {
  N <- 100
  x <- rnorm(N, mean = 50, sd = 2.3)
  y <- runif(N, min = 0, max = 100)
  z <- runif(N, min = 4, max = 70)
  luci.frame <- data.frame(x, y, z)
  
  output$graph <- renderPlotly({
    plot_ly(
      type = "scatter3d",
      mode = "markers",
      data = luci.frame,
      x = ~ x,
      y = ~ y,
      z = ~ z
    ) %>%
      layout(scene = list(camera = list(
        eye = list(
          x = 1.25,
          y = 1.25,
          z = 1.25
        ),
        center = list(x = 0,
                      y = 0,
                      z = 0)
      ))) %>%
      onRender("
      function(el, x){
  var id = el.getAttribute('id');
  var gd = document.getElementById(id);
  Plotly.plot(id).then(attach);
  function attach() {
    var cnt = 0;
    
    function run() {
      rotate('scene', Math.PI / 180);
      requestAnimationFrame(run);
    } 
    run();
    
    function rotate(id, angle) {
      var eye0 = gd.layout[id].camera.eye
      var rtz = xyz2rtz(eye0);
      rtz.t += angle;
      
      var eye1 = rtz2xyz(rtz);
      Plotly.relayout(gd, id + '.camera.eye', eye1)
    }
    
    function xyz2rtz(xyz) {
      return {
        r: Math.sqrt(xyz.x * xyz.x + xyz.y * xyz.y),
        t: Math.atan2(xyz.y, xyz.x),
        z: xyz.z
      };
    }
    
    function rtz2xyz(rtz) {
      return {
        x: rtz.r * Math.cos(rtz.t),
        y: rtz.r * Math.sin(rtz.t),
        z: rtz.z
      };
    }
  };
}
    ")
  })
}

shinyApp(ui, server)

我在 Rstudio 的控制台中没有收到任何错误

我也尽量隔离代码，避免使用Shiny（另存为HTML）在 Chrome 中，我在打开 Debugging

时遇到渲染错误

这是第二个代码（没有闪亮）

#library(shiny)
library(plotly)
library(htmlwidgets)

N <- 100
x <- rnorm(N, mean = 50, sd = 2.3)
y <- runif(N, min = 0, max = 100)
z <- runif(N, min = 4, max = 70)
luci.frame <- data.frame(x, y, z)

plot_ly(
  type = "scatter3d",
  mode = "markers",
  data = luci.frame,
  x = ~ x,
  y = ~ y,
  z = ~ z
) %>%
  layout(scene = list(camera = list(
    eye = list(
      x = 1.25,
      y = 1.25,
      z = 1.25
    ),
    center = list(x = 0,
                  y = 0,
                  z = 0)
  ))) %>%
  onRender("
      function(el, x){
  var id = el.getAttribute('id');
  var gd = document.getElementById(id);
  Plotly.plot(id).then(attach);
  function attach() {
    var cnt = 0;
    
    function run() {
      rotate('scene', Math.PI / 180);
      requestAnimationFrame(run);
    } 
    run();
    
    function rotate(id, angle) {
      var eye0 = gd.layout[id].camera.eye
      var rtz = xyz2rtz(eye0);
      rtz.t += angle;
      
      var eye1 = rtz2xyz(rtz);
      Plotly.relayout(gd, id + '.camera.eye', eye1)
    }
    
    function xyz2rtz(xyz) {
      return {
        r: Math.sqrt(xyz.x * xyz.x + xyz.y * xyz.y),
        t: Math.atan2(xyz.y, xyz.x),
        z: xyz.z
      };
    }
    
    function rtz2xyz(rtz) {
      return {
        x: rtz.r * Math.cos(rtz.t),
        y: rtz.r * Math.sin(rtz.t),
        z: rtz.z
      };
    }
  };
}
    ")

我在 onRender 上遗漏了什么？

更新：感谢@ismirsehregal 将 Plotly.plot 更改为 Plotly.update 的更新您可以查看已接受的答案

如果你需要没有Shiny的版本，你可以使用这个代码

library(plotly)
library(htmlwidgets)

N <- 100
x <- rnorm(N, mean = 50, sd = 2.3)
y <- runif(N, min = 0, max = 100)
z <- runif(N, min = 4, max = 70)
luci.frame <- data.frame(x, y, z)

PLT <- plot_ly(
  type = "scatter3d",
  mode = "markers",
  data = luci.frame,
  x = ~ x,
  y = ~ y,
  z = ~ z
) %>%
  layout(scene = list(camera = list(
    eye = list(
      x = 1.25,
      y = 1.25,
      z = 1.25
    ),
    center = list(x = 0,
                  y = 0,
                  z = 0)
  ))) %>%
  onRender("
      function(el, x){
  var id = el.getAttribute('id');
  var gd = document.getElementById(id);
  Plotly.update(id).then(attach);
  function attach() {
    var cnt = 0;
    
    function run() {
      rotate('scene', Math.PI / 1000);
      requestAnimationFrame(run);
    } 
    run();
    
    function rotate(id, angle) {
      var eye0 = gd.layout[id].camera.eye
      var rtz = xyz2rtz(eye0);
      rtz.t += angle;
      
      var eye1 = rtz2xyz(rtz);
      Plotly.relayout(gd, id + '.camera.eye', eye1)
    }
    
    function xyz2rtz(xyz) {
      return {
        r: Math.sqrt(xyz.x * xyz.x + xyz.y * xyz.y),
        t: Math.atan2(xyz.y, xyz.x),
        z: xyz.z
      };
    }
    
    function rtz2xyz(rtz) {
      return {
        x: rtz.r * Math.cos(rtz.t),
        y: rtz.r * Math.sin(rtz.t),
        z: rtz.z
      };
    }
  };
}
    ")

R plotly 4.10.0 recently updated the underlying plotly.js library from v1.57.1 to v2.5.1. This includes many breaking changes - With version 2.0 of plotly.js the function Plotly.plot was dropped.

要恢复旧行为 Plotly.plot 可以替换为 Plotly.update:

library(shiny)
library(plotly)
library(htmlwidgets)

ui <- fluidPage(
  plotlyOutput("graph")
)

server <- function(input, output, session) {
  N <- 100
  x <- rnorm(N, mean = 50, sd = 2.3)
  y <- runif(N, min = 0, max = 100)
  z <- runif(N, min = 4, max = 70)
  luci.frame <- data.frame(x, y, z)
  
  output$graph <- renderPlotly({
    plot_ly(
      type = "scatter3d",
      mode = "markers",
      data = luci.frame,
      x = ~ x,
      y = ~ y,
      z = ~ z
    ) %>%
      layout(scene = list(camera = list(
        eye = list(
          x = 1.25,
          y = 1.25,
          z = 1.25
        ),
        center = list(x = 0,
                      y = 0,
                      z = 0)
      ))) %>%
      onRender("
      function(el, x){
  var id = el.getAttribute('id');
  var gd = document.getElementById(id);
  Plotly.update(id).then(attach);
  function attach() {
    var cnt = 0;
    
    function run() {
      rotate('scene', Math.PI / 180);
      requestAnimationFrame(run);
    } 
    run();
    
    function rotate(id, angle) {
      var eye0 = gd.layout[id].camera.eye
      var rtz = xyz2rtz(eye0);
      rtz.t += angle;
      
      var eye1 = rtz2xyz(rtz);
      Plotly.relayout(gd, id + '.camera.eye', eye1)
    }
    
    function xyz2rtz(xyz) {
      return {
        r: Math.sqrt(xyz.x * xyz.x + xyz.y * xyz.y),
        t: Math.atan2(xyz.y, xyz.x),
        z: xyz.z
      };
    }
    
    function rtz2xyz(rtz) {
      return {
        x: rtz.r * Math.cos(rtz.t),
        y: rtz.r * Math.sin(rtz.t),
        z: rtz.z
      };
    }
  };
}
    ")
  })
}
