[igraph] Maximum Spanning Tree with igraph

[Leonardo Mazzoni]

Dear all,

I am currently doing a part of my PhD project applying the concept of 
Hidalgo et al. (2007) to find product space at a regional level. I have 
a nxn symmetric matrix and I would like to obtain the graphical 
representation (the network), using the technique of Maximum Spanning 
Tree.
In igraph there is the function Minimum Spanning Tree. Could you please 
suggest me a code in R to use the package igraph to find the Maximum 
Spanning Tree?

thank you in advance for your help!
all the best

Leonardo
