在Rmarkdown中不能使用

[zigner-song]

能否考虑用一个只返回静态图片的功能？ 参考一下在Rmardown里添加wordcloud2结果的方法

    library(htmlwidgets)
    install.packages("webshot")
    webshot::install_phantomjs()
    library(wordcloud2)
    hw = wordcloud2(demoFreq,size = 3)
    saveWidget(hw,"1.html",selfcontained = F)
    webshot::webshot("1.html","1.png",vwidth = 700, vheight = 500, delay =10)
