You are doing something wrong. (It would be much easier to tell what, if
you showed me what you are doing, btw.)
G.
library(igraph)
df <- data.frame(id=sample(letters[1:5]), attr=1:5,
stringsAsFactors=FALSE)
df
# id attr
# 1 b 1
# 2 c 2
# 3 a 3
# 4 e 4
# 5 d 5
g <- graph.ring(5)
V(g)$name <- letters[1:5]
V(g)[df$id]$attr <- df$attr
get.data.frame(g, what="vertices")
# name attr
# a a 3
# b b 1
# c c 2
# d d 5
# e e 4
