[igraph] only display labels for some vertex in igraph with R

[Qi He]

Dear all,

I am using the below R commends to plot graph.

plot(net,layout=layout.fruchterman.reingold, vertex.color="red",vertex.size=10,vertex.label=NA)

plot(net,layout=layout.fruchterman.reingold, vertex.color="red",vertex.size=10,vertex.label=V(net)$name, vertex.label.degree=pi/2,vertex.label.dist=0.7)

However, the above command either does not display labels for vertex at all or display labels for all vertex. 

Could I just display labels for some vertex with certain names? For example, I just want to display label "P53" for a gene vertex whose name is "P53" and ignore the labels of other vertex. 

Thanks much

Dave
