Code

Condition
  Error in `warn_version()`:
  ! This graph was created by a now unsupported old igraph version.
    Call upgrade_graph() before using igraph functions on that object.

we can upgrade from 1.0.0 to 1.5.0, on the fly

Code
  g <- oldsample_1_0_0()
  graph_version(g)
Output
  [1] 3
Code

Message
  This graph was created by an old(er) igraph version.
    Call upgrade_graph() on it to use with the current igraph version
    For now we convert it on the fly...
Output
