Merge two sets of plotly point annotations

Appends extra annotations to annos, skipping any that already describe the same point and text so a point selected by hand and also matched by a highlight value is only labelled once.

Usage

merge_annotation_sets(annos, extra)

Arguments

annos

List of plotly annotation objects, or NULL.

extra

List of plotly annotation objects to append, or NULL.

Value

The combined list of annotation objects, or NULL when both are empty.

length(merge_annotation_sets(a, b))
#> [1] 2
