从R中的Plotly导出PNG文件 [英] Exporting PNG files from Plotly in R

问题描述

如何使用代码从R导出绘图图作为图像? (不使用图表上的导出按钮.)

How can I export a Plotly chart as a image from R using code? (Not using the export button on the chart).

例如，从Plotly网站上的以下代码创建此图表:

For example, this code from the Plotly site, create this chart:

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)

如何将其另存为图像?

官方网站在python中有此材料，但我没有找到在R中类似.

The official site has this material in python, but I didn't find something similar in R.

推荐答案

有一个export功能，可让您保存图像而无需连接到plotly服务器.您可以在完整打包doc 中找到它:

There is a export function which allows you to save images without the need to connect to plotly servers. You can find it in the plotly package doc:

p <- plot_ly(...)
export(p, file = "image.png")

您甚至可以通过将扩展名选择为.png，jpeg或.pdf来更改输出的文件类型.

You can even change the file type of output by selecting the extension as .png, jpeg or .pdf.

您还可以将图像保存在html文件中，该文件可让您通过htmlwidgets::saveWidget体验plotly的缩放或显示批注:

You can also save the image in html file which allows you the plotly experience like zooming or showing annotations by using htmlwidgets::saveWidget:

p <- plot_ly(...)
htmlwidgets::saveWidget(p, file = "image.html")
