Package sna, network et igrpah

Bonjour à vous. Je suis à mes premiers pas avec R, j'utilise les packages network, sna et igraph (du moins je tente d'utiliser).
J'ai réalisé un réseau à partir de la matrice suivante, avec les commandes suivantes:

Je voudrais à présent assigner à mes nœuds les noms suivants:

Code:

"FLIP","ALDO","FK","REMS","CLINEX","KO","ZORO","2F","COJAK","ALPHA","MERT","DIGIT","QAZI","FRER","MONO","G403","LIPS","BOIT","ARTHUR","VIN","BO","PELE","L10","AL","M20","NEZ","P40","E66","2L","NARINE","O203","PP","PIRAT","P274","P277","EPIS","Z","A330","NEIG","MA","ALPHAF","DIANA","2T","P360","PUNK","G400","MARILIN","K431","L11","M21","O30","FOFOL"

De plus, pour certaines analyses ou manipulations, j'obtiens l'erreur suivante :

Code:

Error"la fonction demandé": Not a graph object

comment puis-je transformer mon network en graph object?

J'aurais également besoin pour la suite de transformer mes données en "edge list", comment puis-je faire cela ?

Enfin si quelqu'un peut me donner des liens pour des tutoriels pour ces packages.

Merci à vous pour toute aide apportée.
