How to save adjacency matrix with "get.adjacency ()" in R, with iGraph and RStudio?

Question

Is it possible to save the adjacency matrix after "get.adjacency ()" as an adjacency matrix in R? I tried

test <- get.adjacency(network)

but i get an error

Error in View : cannot coerce class "structure("dgCMatrix", package = "Matrix")" to a data.frame. 

I am using RStudio and the iGraph package.

Answer 1

Try using sparse=FALSEin a callget.adjacency(...)

g <- graph.full(5)
test <- get.adjacency(g)
class(test)
# [1] "dgCMatrix"
# attr(,"package")
# [1] "Matrix"

test <- get.adjacency(g,sparse=FALSE)
class(test)
# [1] "matrix"
