Thank for your impressive work,

Do you know if there is any possibility to nicely save the cloud in png or svg format? Being able to change the resolution and such would be really nice :)

Cheers

Currently, wordcloud2 can be exported by Rstudio:

Use the Export -> Save As Image menu within the RStudio Viewer (this will let the user export a PNG of whatever size they need).

I'm still looking for a good method for exporting from R codes.

I'll write a new function to solve exporting. You can try it like this:

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 = 1992, vheight = 1744, delay =10)
