orca in R failed

[brainfo]

I used rstudio-server with rmarkdown. and I just wrote orca(fig, "time_vocano.pdf") in .Rmd file. the error is this:

Warning: 'orca' is deprecated.
Use 'kaleido' instead.
See help("Deprecated")

should I use orca_server? Or what could I do to export static figures from R-plotly? Thanks!

Looking to bump this. Did kaleido work for you? Do people have another solution for Plotly in R?
