Yes; you can either read your input files into an R data frame and then use 
graph.data.frame to construct a graph, or use the read.graph function with the 
"ncol" format -- which is essentially a named edge list. igraph will then 
assign numeric IDs to the nodes automatically and store the original names in 
the "name" vertex attribute.
