R wordcloud2 letterCloud showing only the background

Question

My Rstudio version is 3.4.1 64-bit on Win10. I have installed the package wordcloud2 via the commands

install.packages('devtools')
devtools::install_github("lchiffon/wordcloud2")

And things went smoothly. Then I tried running the example from the official documentation on R console:

letterCloud(demoFreq, word='R')

Then what comes up is only the background colour, and nothing else at all. Web browser is Chrome 59.0 64-bit. However, the other function wordcloud works quite well.

I suppose this should be a common problem, so hopefully somebody can give me some help, thanks.

Answer 1

The issue is already raised here: https://github.com/Lchiffon/wordcloud2/issues/12.

Unfortunately, no solution is yet on the table other than refreshing your window.

Also, IE and Firefox seems to work better than chrome.

Answer 2

You can now reinstall it from GitHub using:

devtools::install_github("lchiffon/wordcloud2")

and it works well. :)
