如何保存通常方法无法保存的图

问题描述

这可能是该问题的更一般版本(如何保存grgough图表为.png ).

This might be a more general version of this question (How to save ggrough chart as .png).

我正在使用RStudio.通常，我可以按常规方式(png()，jpeg()和ggsave()保存我的图.

I am using RStudio. I can typically save my plots usual ways (png(), jpeg(), and ggsave().

但是，我遇到了在RStudio Viewer中渲染图的情况，但是上述保存命令不起作用.

However, I have encountered situations where the plot renders in the RStudio Viewer, but these aforementioned saving commands do not work.

以下是remiotic页上的示例，该页面位于 https://timelyportfolio.github.io/remiotic/:

Here is an example taken from the remiotic page at https://timelyportfolio.github.io/remiotic/:

library(remiotic)
remiotic(
    # lines expected to be an array of arrays
    #  for now do it the really ugly way
    #  but should be able to fix this fairly easily
    data = list(
        list(
            group = "A",
            coordinates = lapply(0:10, function(x) list(x=x, y=runif(1)))
        )
    ),
    frame = "XYFrame",
    props = list(
        shape = "lines",
        xAccessor = "x",
        yAccessor = "y",
        xExtent = c(0, 10),
        yExtent = c(0, 1),
        lineStyle = list(stroke = "#629"),
        margin = list(
            top = 20,
            right = 40,
            bottom = 50,
            left = 50
        ),
        axes = list(
            list(orient = "left"),
            list(orient = "bottom")
        )
    ),
    width = "100%"
)

我尝试将jpeg("file")，png("file")和pdf("file")放在此代码之前，并将dev.off()放在之后.前两个不创建文件，第三个不创建文件，但是由于它没有将绘图保存到其中，因此我无法打开该文件.我有一台Mac；如果我将x11()放在前面，它将打开新窗口，但会在RStudio Viewer中渲染图.

I have tried putting jpeg("file"), png("file"), and pdf("file") before this code and dev.off() after. The first two do not create a file and the third does, but I can't open the file as it didn't save the plot to it. I have a Mac; if I put x11() in front, it opens the new window, but renders the plot in the RStudio Viewer.

如何使用代码(而不是RStudio的导出按钮)保存这样的图形?

How can I save a plot like this using code (and not RStudio's export button)?

推荐答案

rg <- remiotic(...)
htmlwidgets::saveWidget(rg, "remplot.html")

或者Webshot软件包将允许捕获为png.

Or Webshot package would allow for capture as png.

library(webshot)
webshot("remplot.html", "remplot.png")
