Please see doc/Illustrations.pdf for short graphical illustration of this package.

The main function in this package is InteractiveIGraph - in fact, all package is all about this function.

Warning

The system is tested only in Windows (sorry for that).

This package is based on igraph, grDevices packages, therefore it has their advantages and disadvantages.

First of all, InteractiveIGraph works only on Windows and X11(type = "Xlib") screen devices, therefore if working with RStudio you should activate one of the devices. Secondly, with the large graphs, reploting becomes really annoying, so, it is really for small graphs. On the other hand customising large graphs in console might by even more annoying.

This package has several huge advantages comparing with tkplot. Firstly, it is much more flexible. You can change any attributes or vertexes or edges. Moreover, you may easily create any extra functionality in menu commands. On the other hand, it is not so much intuitive and stable. In the case of wrong entrees it may crash.

Examples

# this is a regular igraph object
gOrg <- erdos.renyi.game(15, 1/10,  directed = TRUE)
plot(gOrg) 

# this is an 'InteractiveIGraph' object, up till now there is not much difference. 
# Just some extra attributes.
g = InteractiveIGraph.Constructor(gOrg)
g = plot(g) 

# now it is interactive. Please enjoy :)
if(interactive()){
  g = InteractiveIGraph(gOrg)
}
# p.s. if you want to save changes please press 'q' while ruining InteractiveIGraph().

# Select some vertices and apply commands, for example 'a', 'A', or 'g', 'b'.
# you may change any attributes by key 'ctrl-F' and then typing attributes command,
# for example 'color="green"'
# (it will work only on selected vertices).

# you may run any command by key 'ctrl-C' and typing command, for example 'print(V(g)$name)'

# with key 's' you can change selection mode - in this way you can select multiple vertices.
