Layout attribute "template"

After playing with plotly.py themes and templates options, I was wondering if it was possible to achieve the same result with plotly for R.

Although there is no themes available in R, I thought I could use the template options from the python themes and use them in a template in R.

In the plotly R figure reference, there is under "layout" the item "template" with the following description:

Parent: layout
Type: number or categorical coordinate string
Default attributes to be applied to the plot. Templates can be created from existing plots using Plotly.makeTemplate, or created manually. They should be objects with format: {layout: layoutTemplate, data: {[type]: [traceTemplate, ...]}, ...} layoutTemplate and traceTemplate are objects matching the attribute structure of layout and a data trace. Trace templates are applied cyclically to traces of each type. Container arrays (eg annotations) have special handling: An object ending in defaults (eg annotationdefaults) is applied to each array item. But if an item has a templateitemname key we look in the template array for an item with matching name and apply that instead. If no matching name is found we mark the item invisible. Any named template item not referenced is appended to the end of the array, so you can use this for a watermark annotation or a logo image, for example. To omit one of these items on the plot, make an item with matching templateitemname and visible: FALSE.

I have tried passing several possible argument to the template option of layout to no effect. Is there an option to use a template at the moment in plotly.R, and if so what is the proper syntax for the argument to pass?

Thank you very much for your help.

Inizia dalla voce layout/template del riferimento alle figure R e confrontala con la documentazione collegata sui template Python. Determina se plotly.R espone già la gestione dei template; il lavoro è completato quando viene documentata la sintassi dell’argomento supportato oppure vengono identificate l’implementazione mancante e i test necessari.
