igraph; distance between nodes

I'm using igraph 

g <- graph_from_adjacency_matrix(adj2, mode = "directed") 

plot.igraph(g, vertex.size = 0.01, edge.arrow.size = 0.09, vertex.label.cex = 0.3, vertex.color = "white", vertex.shape = "none")

The problem that I have is that some nodes fall pretty close from each other and when I print it is hard to see some nodes.

I want to somehow to set a bigger distance between nodes that fall close (the central cluster of nodes, for example).

thanks!

You can use some layouts to extract the network and make it more readable. This can be done by different layouts, here an example for the fruchterman.reingold algorithm:

plot.igraph(g, layout =  layout.fruchterman.reingold, vertex.size = 0.01, edge.arrow.size = 0.09, vertex.label.cex = 0.3, vertex.color = "white", vertex.shape = "none")

Another example would be to use the layout=layout.auto. You have to look which layout fits better to your data.

You can read more about different layouts in the CRAN documentation igraph
