使用R和plot.ly - 如何将输出脚本保存为网页

Question

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

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)

生成此图形后,当我单击R-Studio的"绘图"窗口中的"导出"按钮时,它为我提供了将绘图保存为网页的选项.如何编写将生成的图表保存为网页的过程？我的最终目标是从bash脚本中迭代运行Rscripts以生成多个网页.

Answer 1

将plot_ly对象分配给变量,然后使用htmlwidgets::saveWidget()保存实际文件,如下所示:

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")
