Examples

  V <- LETTERS[1:4]
  edL1 <- vector("list", length=4)
  names(edL1) <- V
  for(i in 1:4)
    edL1[[i]] <- list(edges=c(2,1,4,3)[i], weights=sqrt(i))
  gR <- graphNEL(nodes=V, edgeL=edL1)

  gX <- removeEdge("A", "B", gR)

  set.seed(123)
  g <- randomEGraph(V=letters[1:5],edges=5)
  g2 <- removeEdge(from=c("a","b"), to=c("d","c"), g)
