set_node_attr {DiagrammeR} | R Documentation |
From a graph object of class dgr_graph
or a node
data frame, set node attribute properties for one or more nodes.
set_node_attr(x, nodes = NULL, node_attr, values)
x |
either a graph object of class |
nodes |
an optional vector of node IDs for filtering list of nodes present in the graph. |
node_attr |
the name of the attribute to set. |
values |
the values to be set for the chosen attribute for the chosen nodes. |
either a graph object of class dgr_graph
or a node
data frame, depending on what type of object was supplied to x
