importing network in Statnet in R

Question

I am new to STATNET and know nothing about it. I have a data set which has 3 columns. The first and second column contain nodes whereas the third contains edge value. How should I import this to STATNET? I suspect I need to convert this dataset to a matrix. How can I do that in R?

Answer 1

No need to change it into a matrix, you can use a weighted edgelist right away. Try something like

library(statnet)

dat <- structure(
    list(a = c(1, 2, 4), b = c(2, 3, 5), c = c(10, 1, 1)),
    .Names    = c("a", "b", "c"),
    row.names = c(NA, -3L),
    class     = "data.frame"
)


g <- as.network(
    dat,
    ignore.eval = FALSE,
    names.eval  = 'weight',
    matrix.type = 'edgelist',
    directed    = FALSE
    )
