rescale_edge_attrs_ws {DiagrammeR} | R Documentation |
From a graph object of class
dgr_graph
, take a set of numeric values for
edge attributes specified in a selection of edges,
rescale to a new numeric or color range, then write
a new set of edge attribute values.

|
edge_attr_from |
the edge attribute containing numeric data that is to be rescaled to new numeric or color values. |
edge_attr_to |
the name of the new or existing edge attribute that will contain the scaled values. If the edge attribute exists for the selected edges, rescaled values will replace any existing values. |
to_lower_bound |
the lower bound value for the set of rescaled values. This can be a numeric value or an X11 color name. |
to_upper_bound |
the upper bound value for the set of rescaled values. This can be a numeric value or an X11 color name. |
from_lower_bound |
an optional, manually set lower bound value for the set of values to be rescaled. If not set, the minimum value of the set of values to be rescaled will be used. |
from_upper_bound |
an optional, manually set upper bound value for the set of values to be rescaled. If not set, the minimum value of the set of values to be rescaled will be used. |
