This function splits the [-1,1] interval into 2000 smaller
ones and matches each value of the diff vector to a specific hex color
code, using a spline interpolation of the colors as defined in the col
parameter.
get_node_colors(net, diff, col)
| net | an igraph graph object with the node names defined in |
|---|---|
| diff | numeric vector. Every value is in the [-1,1] interval and
represents the average activity difference of each node. The node names have
to be specified in the names attribute of the given |
| col | a character vector of colors to do the color interpolation in the [-1,1] interval. Usually a two-element vector specifying the colors matching the start and end of the interval (-1 and 1 respectively) or a three-element vector specifying the colors matching the values -1, 0 and 1 (can be more of course, you get the idea). |
a character vector of hex color codes where the names attribute
corresponds to the nodes of the given igraph object. Will be used to fill in
the V(net)$color property of the net object. If there are nodes
that are part of the network object net but not present in the diff
vector, then a NA value will be given for the color of these nodes.
