R ggiraph-运行.R文件时没有打印

执行.R文件时如何获取图形？文件（

test.r

）如下所示：

library(ggplot2)
library(ggiraph)
gg <- ggplot(data = mtcars, aes(x = mpg, y = wt, color = factor(cyl)))
gg1 <-  gg + geom_point_interactive(aes(tooltip = gear), size = 5)
ggiraph(code = print(gg1))

R

生成一个临时的.html文件，然后生成一个

gvfs open

进程来查看该文件（这将打开Firefox）。当您从命令行运行脚本时，

R

退出并在Firefox进程有机会完全加载之前清理其临时文件。您可以通过以下操作看到这一点

$ R -q --interactive < test.R
> library(ggplot2)
> library(ggiraph)
> gg <- ggplot(data = mtcars, aes(x = mpg, y = wt, color = factor(cyl)))
> gg1 <-  gg + geom_point_interactive(aes(tooltip = gear), size = 5)
> ggiraph(code = print(gg1))
Save workspace image? [y/n/c]:

谢谢，您的第二个解决方案非常有效！由于一些小错误，我还安装了带有“sudo apt get install PANDOC”的PANDOC
