使用 R 和 plot.ly - 如何编写脚本将输出保存为网页

问题描述

我想使用 R 和 plot.ly 制作一些交互式图表.当我在 R-Studio 中运行以下代码时，它会生成一个交互式图表.

I want to make some interactive graphs using R and plot.ly. When I run the following code in R-Studio, it produces an interactive graph.

library(plotly)
set.seed(100)
d <- diamonds[sample(nrow(diamonds), 1000), ]
plot_ly(d, x = carat, y = price, text = paste("Clarity: ", clarity),
    mode = "markers", color = carat, size = carat)

生成此图后，当我单击 R-Studio 绘图窗口中的导出"按钮时，我可以选择将绘图保存为网页.如何编写将生成的绘图保存为网页的过程?我的最终目标是从 bash 脚本中迭代地运行 Rscripts 以生成多个网页.

After producing this graph, when I click on the "Export" button in the Plot window of R-Studio, it gives me the option to save the plot as a webpage. How can I script the process of saving produced plots as webpages? My ultimate goal is to run Rscripts iteratively from inside a bash script to produce multiple webpages.

推荐答案

将 plot_ly 对象赋值给一个变量，然后使用 htmlwidgets::saveWidget() 保存实际文件，如下所示:

Assign the plot_ly object to a variable and then use htmlwidgets::saveWidget() to save the actual file, like so:

library(plotly)
set.seed(100)
d <- diamonds[sample(nrow(diamonds), 1000), ]
p <- plot_ly(d, x = carat, y = price, text = paste("Clarity: ", clarity),
             mode = "markers", color = carat, size = carat)
htmlwidgets::saveWidget(as_widget(p), "index.html")
