Wordcloud failing in Rmarkdown tabsets about wordcloud2

[gaospecial]

Hi @samuelhuerga,

I found a way to slove my problem.

Just install my fork by devtools::install_github("gaospecial/wordcloud2"), and then it works.

The following test code

library(wordcloud2)
wordcloud2(data = head(demoFreq,3))
wordcloud2(head(demoFreq,3), color = "random-light", backgroundColor = "grey")
wordcloud2(head(demoFreq,6), color = "random-light", backgroundColor = "white")

will give the result:

I don't know why it works, as I just update the wordcloud2.js library to the latest version.

May this can be helpful.

Thanks Gao! I found that your solution (using your fork) worked for me in a 'standard' RMarkdown document, but not when used with tabset within flexdashboard. Here's a repo I quickly created producing the example:

Any idea if this is more an issue with flexdashboard perhaps?

A bit old, but for @martinctc: something that got all of the wordclouds to show up for me was appending {.active} after each sub-header (e.g., ### Tab 1 {.active}.

Happens the same here.

If I use two wordclouds in an rmd knitted to HTML, only the first one is shown.

Same here.

here I have a alternative solution.

Use the following function.

#' Webshot a widget and place it in place with markdown syntax
#'
#' @param widget a html widget, i.e. generated by wordcloud2 pacakge
#' @param path figure webshot storage place
#'
#' @return
#' @export
#'
#' @examples
markdown_widget <- function(widget,path=getwd(),filename="file.png"){
  require(htmlwidgets)
  require(webshot)
  saveWidget(widget,"tmp.html",selfcontained = F)
  file <- paste(path,filename,sep = "/")
  webshot("tmp.html",file,delay = 5,vwidth = 1024,vheight = 768)
  file.remove("tmp.html")
  paste0("![",file,"](",file,")\n\n") %>% cat()
}

when in markdown file, insert a chunk like this:

```{r results="asis"}
widget <- wordcloud2(...)
markdown_widget(widget,path=".",filename="wordcloud.png")
```

then in your markdown file, the figure will finally show up.

thank you @gaospecial !

I wonder what is causing the issue. Outdated package installing via "wordcloud2" directly?

[eimennin]

Thanks, @gaospecial I have had this problem for years!

Does anyone know why lettercloud() doesn't work?

May be the backend wordcloud javascript has bug, as its version is very low.
