lbocken commented 6 years ago

I have Rstudio v. 1.2.747 on Windows 10

From : https://www.r-graph-gallery.com/196-the-wordcloud2-library/ I tried the following code chunk without success, Ok for html but png is a white file... `

install webshot

library(webshot) webshot::install_phantomjs()

Make the graph

my_graph=letterCloud(demoFreq,"@",1)

save it in htmllibrary("htmlwidgets")

saveWidget(my_graph,"tmp.html",selfcontained = F)

and in png

webshot("tmp.html","fig_1.png", delay =5, vwidth = 480, vheight=480) `

Thank you very much for your help !

Solved by #8?

Nope, not solved by #8. I used the steps above, and it only saves a blank white page. The image renders fine in the Viewer pane of RStudio, but it's critical to be able to export to an image file (pdf, png, jpeg, etc.).
