Hi,
I assume that "C1 C2" is the header of your file and they are not actual nodes.
Delete that line and use read.graph(..., format="ncol") to read the file into
igraph. This will not create you a bipartite graph yet, only a "simple" graph,
but the only thing you need to do in order to make it bipartite is to assign a
"type" vertex attribute with TRUE/FALSE values to define the two parts of the
graph. This can be done based on the vertex names of your graph:
> g <- read.graph("sample1.txt", format="ncol")
> V(g)$type <- substr(V(g)$name, 1, 1) == "d"
