wordcloud and htmlwidgets::saveWidget

[davidgohel]

Thanks for your package, it's very useful.

I met an issue when using htmlwidgets::saveWidget. Could you help on that?

library(wordcloud2)
xx <- wordcloud2(data = demoFreq)
htmlwidgets::saveWidget(widget = xx, file = "test.html", selfcontained = TRUE)

When opening the file test.html, nothing is displayed. An javascript error can be read in the js console: Uncaught TypeError: canvas.getBoundingClientRect is not a function(…)

I've found this problem, try this:

htmlwidgets::saveWidget(widget = xx, file = "test.html", selfcontained = FALSE)

Looking forward to opening a issue in htmlWidges ...

Yes, if using selfcontained = FALSE I have what's expected.

Hi,

Is that a wontfix? We wanted self-contained files because that was the only format supported on a portal (MS sharepoint).

Try this function:

simpleFix = function(inputFile, outputFile){
  a = readLines(inputFile)
  output = paste(a, collapse = "\n")
  output = gsub(">\n\n</div>","></div>",output)
  writeLines(output, outputFile)
  invisible(NULL)
}

library(wordcloud2) 
library(htmlwidgets)

m <- wordcloud2::wordcloud2(wordcloud2::demoFreq)
htmlwidgets::saveWidget(m, file = "wordcloud2.html", selfcontained = TRUE)
simpleFix("wordcloud2.html", "wordcloud2.html")

pandoc leave some strange output for self-contained html.
