Incorporate plot_ly() config arguments ? #2

After playing with my alluvial plot, I would like to save it as a png. But the resulting image is very small (700 x 450). I would have liked to use plot_ly() config arguments (https://plotly-r.com/exporting-static-images.html) such as: plot_ly() %>% config( toImageButtonOptions = list( format = "svg", filename = "myplot", width = 600, height = 700 ) )

But these have no effect on a paracats object... Could this be incorporated or an option to set the size of exports of paracts objects directly?

yes so this does not work, because it is a different package, but you can use the the Rstudio export button in the viewer window to create any screenshot in a reasonable resolution that you like. If you are looking for an automated solution you can use the package webshot which integrates well with knitr. You can find a detailed description here. If at one point the R plotly package will include the parcats trace, I might add a a wrapper for it to easyalluvial. But I do not think this would add much additional functionality besides it being easier to use for people that already know the plotly R package API.
