[R] Questons about 'igraph' package

I am using 'igraph' to make some plots. The problem I got is that I don't
know how to label the nodes with gene names.

My sample code:

## suppose I have 100 gene (nodes) ##
graph <- set.vertex.attribute(graph, "color",
graph <- set.vertex.attribute(graph, "name", value=genelist)
The 'color' attribute does work, the nodes are red and green, but the 'name'
attribute doesn't work, I still have the numeric id on each node (0-99).

Can anyone tell me how to solve this problem?

Thank you,
