Invalid (non-finite or NaN) vertex

Reprex of error:

Use the email_nodes.csv and email_edges.csv tables from https://michaelgastner.com/DAVisR2021/chap-tidygraph.html. If running the code shown in the ebook:

email_directed_netw <-
  tbl_graph(nodes = email_nodes, edges = email_edges)

...then the command run successfully.

However, if one uses:

email_directed_netw <-
  tbl_graph(nodes = head(email_nodes), edges = head(email_edges))

...then the error is:

Error in (function (edges, n = max(edges), directed = TRUE)  : 
  At core/constructors/basic_constructors.c:72 : Invalid (non-finite or NaN) vertex index when creating graph. Invalid value

If using head() results in an incomplete network, and that is the issue, then a better error message pointing to the problem would be very helpful.
