[PAllen0518]

Article under address ( https://plotly.com/r/static-image-export/ ) needs to be updated to reflect the deprecation of orca:

library(plotly)
 if (!require("processx")) install.packages("processx")
fig <- plot_ly(z = ~volcano) %>% add_surface()
orca(fig, "surface-plot.svg")

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

Platform: x86_64-w64-mingw32/x64 (64-bit)

other attached packages:

Yes please, this just cost me a couple of hours trying to add orca inside my Docker environment. Quite annoying to find out when everything is configured correctly, at the end you are presented with the message that orca is outdated :(
The documentation should contain the article for the installation of https://github.com/plotly/Kaleido/ and the save_image/export_image methods by the Kaleido package
