addLegend.color(obj, colvec,  ...)
addLegend.size(obj, sizevec, ...)
addLegend.shape(obj, shapevec, ...)

`obj`	Object of RedPort Class.
`colvec`	Vector with legend colors, either hexadecimal or valid R color names.
`sizevec`	Vector with legend node size, options: > 0 <numeric>.
`shapevec`	Vector with valid shape names: 'ELLIPSE', 'RECTANGLE', 'ROUNDED_RECTANGLE', 'TRIANGLE', 'DIAMOND'.
`...`	Additional arguments passed to RedeR application.

Alternatively, colvec, sizevec and shapevec can be igraph objects with legend information previously set by the functions 'att.setv' and 'att.sete'.

Additional arguments:

type: Legend type. Options: "node" or "edge" (default: "node") <character>.
labvec: Vector with legend labels <character>.
position: Position of the legend in RedeR panel. Options: 'topleft','topright','bottomleft','bottomright' (default: addLegend.color "topright", addLegend.size "bottomleft", and addLegend.shape "bottomright" )<character>.
dxborder: Distance (in pixel) from panel border (default: 5 ) <numeric>.
dyborder: Distance (in pixel) from panel border (default: 5 ) <numeric>.
vertical: Logical value, set vertical/horizontal position of the legend in the app panel (default: TRUE for addLegend.color and addLegend.size and FALSE for addLegend.shape.
ftsize: Font size (in pixel) (default: 8) <numeric>.
title: Legend title <string>.
dxtitle: Distance (in pixel) from legend title to the main axis (default: 35) <numeric>.
size: Legend size; only for addLegend.color and addLegend.shape methods (default: 30) <numeric>.
bend: Legend width/height ratio; only for addLegend.color method (default: 0.85) <numeric>.
col: Legend color; only for addLegend.size and addLegend.shape methods (default: "#000000") <either hexadecimal or valid color name>.
intersp: Legend inter space (only for addLegend.size and addLegend.shape methods) (default: 0) <numeric>.
edgelen: Length of the edges in addLegend.size method (default: 50) <numeric>.
