Examples

V <- letters[1:10]
M <- 1:4
g1 <- randomGraph(V, M, .2)

## Make the labels be the edge weights.  This code is from the vignette
eAttrs <- list()
ew <- edgeWeights(g1)
lw <- unlist(unlist(ew))
toRemove <- removedEdges(g1)
lw <- lw[-toRemove]
names(lw) <- edgeNames(g1)
eAttrs$label <- lw

z <- agopen(g1,"foo", edgeAttrs=eAttrs)
x <- AgEdge(z)  ## list of AgEdge objects
x[[1]]  ## AgEdge
a <- txtLabel(x[[1]])
a ## txtLabel object
