How to store graphs (from the igraph package) in R?

Is it possible to store a set of graphs (from igraph) in vector or other data structure?

I'm trying to do it in this way:

require('igraph')

g1 <- make_tree(10,3)
g2 <- make_tree(30,3)

gs <- c(g1,g2)

as.igraph(gs[1])

but it doesn't work. I got error:

Error in UseMethod("as.igraph") : 
  no applicable method for 'as.igraph' applied to an object of class "list"

You can store them in a list:

gs <- list(g1,g2)
class(gs[[1]])
# [1] "igraph"

The gs[[i]] are igraphs and you don't need to run as.igraph on them.

Also, according to the docs, the as.igraph function can only be used on codeigraphHRG objects.
