mask and letterCloud silently fail

[csteacherd22]

Hello,
I'm enjoying wordcloud2 and hoping to make use of the unique features.
However, the png mask and letterCloud functions have been silently failing.
Also, using the provided example of setting figPath to a png fails as per https://rstudio-pubs-static.s3.amazonaws.com/187645_426d719fae56457f84d767fd6f076a43.html:

figPath = system.file("examples/t.png",package = "wordcloud2")
wordcloud2(demoFreq, figPath = figPath, size = 1.5,color = "skyblue")

Similarly, the "https://www.r-bloggers.com/the-wordcloud2-library/" Peace symbol example command: wordcloud2(demoFreq, figPath = "peace.png", size = 1.5, color = "skyblue", backgroundColor="black")
also silently fails.

This is a small bug I haven't fix so far.

Have you tried to refresh the viewer or open in the browser?

Same problem here. Refreshing helps - thanks!

Sorry Lchiffon, I experience the same issue in Google Chrome (even after reloading the page)... but the code works in IE

I'm using the library to produce png's as a backend service and getting no output for letterCloud and mask generations.

Thanks for the great feature set, would help out if I was more of an R expert, will watch this bug for now.

Mostly a "me too" in February 2018: using the latest R 3.4.3 and RStudio 1.1.419 I get the background image for either letterCloud() or the figPath option of wordcloud2. There are never any words, whether I reload or not. Sending it to Chrome gives just a blank white screen, not even the background.

I face the same problems after installing the latest version of R 3.4.3 and RStudio 1.1.423 (I have updated all packages also). I get only the background of the letter (letterCloud function) or of the mask (wordcloud2 function with figPath option).

It worked on my old version of R, RStudio and packages but unfortunately it did not save the configuration reference. Maybe someone know if there is a configuration who works ?

I'm having the same problem, letterCloud is producing only the background "word" in black, with none of the actual words from the data frame showing. I've tried several different versions of R to no avail.

letterCloud(demoFreq,"R")

However, if I re-install the package directly from git rather than cran, it works!

library(devtools)
devtools::install_github("lchiffon/wordcloud2")
letterCloud(demoFreq,"R")

Same issue here. "wordcloud2" produces a nice image in RStudio that is viewable in markdown and in an html doc after it is knit, but not viewable in a browser (Chrome or Firefox). All packages updated, RStudio 1.1.442, R version 3.4.4 (2018-03-15)

Here's the doc with an invisible image: http://rpubs.com/bmeyer/372805, Session info included within.

I could manage to make it work in Rstudio after installing the package via github as suggested by SarahDawsonStats, but it needs everytime a refresh.
Unfortunately it seems not working in a Shiny application.

Hi all, I ran into the same issue but unfortunately I did not manage to resolve it with SarahDawsonStats' suggestion of downloading the source package. When I reinstall it, I instead get the following error running any type of wordcloud2 output:

Error in yaml.load(readLines(con), error.label = error.label, ...) : argument "error.label" is missing, with no default

Things I have tried so far:

• Install all of the Windows binaries from from the wordcloud2 CRAN page (only the r-release version will work as intended, save for the image/letter mask functionalities. The other 2 will lead to the error above)
• Use alternative sources to install the package
• Perform various fresh installs of the yaml package
• Googled extensively to find solutions to the error mentioned above but to no avail, and most seemed to stem from unrelated issues
• Tried to open the image/letter mask in a browser (as per the author's suggestion). Tried in Chrome, Firefox and IE.
• A fresh install of RStudio + deleting all packages and reinstalling only the bare minimum
• All of the above I tried both with the provided sample dataset (demoFreq) as well as my own textual dataset.

Any help would be greatly appreciated, I'm not sure where I'm going wrong!

I had the same problem with nothing displaying from wordcloud2 when I added the figPath argument. Once I changed my default browser from Chrome to IE (and allowed "blocked content") it worked:

wordcloud2(demoFreq, figPath="logo.jpg")

Sorry, I meet the same problem with MayoIsLife.
I did not manage to resolve it by downloading the source package from github.

When installed the package from CRAN, it will show only background.
If installed the package from github, it will silently failed.

Could anyone help me to solve the issue? I really enjoying using this package.

LetterCloud only returns the word and not the dataset.

[jiristo]

Do not use system.file()

I did this and it works:

figPath <- "/Users/jiristodulka/R/web_scraping/reddit_cannabis/canna_leaf.png"

wordcloud2(demoFreq, figPath = figPath, size = 3,color = "green", backgroundColor = "black")
