This is surprisingly difficult to do. I have already seen:
Plotly as png in knitr/rmarkdown
Embedding plotly output in R markdown
None of these solve the issue and seem to be outdated. Anyone currently doing this or should I abandon the plotly package?
EDIT:
Looking some more, apparently THIS is true from:
https://community.plot.ly/t/use-plotly-offline-to-save-chart-as-image-file/408/6
contacting plotly support resulted in:
community members may only export to PNGs Other formats are
available with the profession plan: https://plot.ly/products/cloud/113
At the moment it is not possible to programatically export an image while using offline, i.e. confirming @jpp
You do have the option to use the camera icon in the mode bar on hover. This worked for me using plotly offline 1.9.3 and chrome, but not Firefox @thauta
