[igraph] Output from degree

[Thomas]

Can anyone please explain why this is happening? With two different  
graphs, the output format from degree() is different. I'd like to  
force the second format (output just one number) on the first graph.

Thank you,

Thomas Chesney

i <- 5

g <- read.table("/Users/thomas/Documents/Datasets/organizations/ 
S1Anonymized.csv",header=FALSE, sep=",", na.strings="NA", dec=".",  
strip.white=TRUE)
g <- graph.data.frame(g, directed=FALSE, vertices=NULL)

degree(g,i)
69
 1

f <- watts.strogatz.game(1, 165, 5, 0.05)
degree(f,i)
[1] 8

str(degree(g,i))
 Named num 1
 - attr(*, "names")= chr "69"

str(degree(f,i))
 num 8
