(regression) plotly.R v4.12.0 no longer renders any figures in knitr/LaTeX

[JElchison]

Hi folks, THANKS for a great library!

plotly.R v4.12.0 seems to have introduced a new regression: Using knitr (LaTeX), all rendered Plotly figures are now empty -- both inside the final compiled PDF, and inside each figure's individual PDF (in /figure/)

The workaround is reverting to v4.11.0

Min working example (test.Rnw):

\documentclass{article}

\begin{document}

<<include=FALSE>>=
library(knitr)
library(remotes)
#remotes::install_version("plotly", version = "4.11.0")  # works
remotes::install_version("plotly", version = "4.12.0")  # leaves empty figure
@

<<label=version, echo=FALSE, fig.keep='last', out.width="5in", crop=TRUE>>=
packageVersion("plotly")
@

Top line -- Figure should be below

<<label=Sepal, echo=FALSE, fig.keep='last', out.width="5in", crop=TRUE>>=
plotly::plot_ly(
  data = iris,
  x = ~Sepal.Length,
  y = ~Sepal.Width,
  type = 'scatter',
  mode = 'markers',
  color = ~Species,
  marker = list(size = 10, opacity = 0.8)
)
@

Bottom line -- Figure should be above

\end{document}

To render, simple save the above snippet as a new file test.Rnw, and click the "Compile PDF" button in RStudio.

Note the absence of figures when using 4.12.0, both:

• in final-compiled PDF (here, test.pdf)
• in each figure's individual PDF (here, /figure/Sepal-1.pdf)

Note that reverting to 4.11.0 allows figures to render properly:

Thanks for reading!

Interesting, thanks for reporting. Do you happen to know what {knitr} uses to take the screenshot? Another workaround would be to use plotly::save_image() to save the static image.

Sadly, screenshots are all handled internal to {knitr}, and my cursory searches didn't turn up anything conclusive.

Gemini thinks it uses the pdf graphical device
