Probably this is a bug, I'll investigate it. Can't you just set all values of the edge attribute at once, using E(g)$rtval <- rtval as a workaround? Btw. it would be great to have some self-contained code that reproduces the problem, in the questions sent to the list, because otherwise it takes nine minutes for me to create some reasonable fake data, and then one minute to answer the question. Sometimes I have one minute to answer a question, but don't have ten minutes. I am sorry to bring this up now in this email, it is a rather general suggestion. More soon.
