[igraph] vertex attribute assignment matching names

[Bob Pap]

Dear all,

 

I found no help in the relevant pages for assigning vertex attributed _making sure that names are properly matched.  Example, V(g)$name lists 50 cities in a non-alphabetical order, whereas I have a data.frame with 50 lines and a 'name' column in alphabetical order having as columns additional vertex attreibutes I would like to assign.

 

Simply doing V(g)$size <- my.data.frame$size does not (as far as I can read from the help pages) guarantee that cities are properly matched by name (V(g)$name and my.data.frame$name respectively).

 

How can I specify that names are correctly mapped? Any suggestion is appreciated.

 

Kind regards,

Bob
