Adding field to feature layer?

[sarahhurley]

Hi there - I am wondering if there is the capability of adding a field to a feature layer through the arcgislayers package? I'm working on setting up a workflow that may require us to add a field to a dataset over time (trying to avoid needing to republish it every time). I've tried to look through the documentation, but I've only found in the "Overwrite Hosted Feature Layer" section of the R-ArcGIS Bridge documentation a line that says "Truncating a service does not change the field definitions or permit us to add or remove fields to it. If you wish to do so, publish a new layer instead."

Thanks for your help!

This is not possible from arcgislayers today. It can be done manually if you are crafty enough with {httr2} !
REST documentation: https://developers.arcgis.com/rest/services-reference/online/add-to-definition-feature-layer-.htm

I'm going to convert this to an issue as a feature request.

A quick note on this capability, though, is that only the owner or admin can perform this operation

Okay - that is good to know, thanks so much!
