I am trying to create a network from the matrix that is attached.
> matrixSelecionada <- read.csv("matrix.csv", header = FALSE)
> matrixSelecionada <- data.matrix(matrixSelecionada)
## changing the values of the matrix
> for (i in 1:nrow(matrixSelecionada)) {
for (j in 1:ncol(matrixSelecionada)) {
if (matrixSelecionada[i,j] < 0.01 || i==j) {
matrixSelecionada[i,j] <- 0
} else if (matrixSelecionada[i,j]>=0.01) {
matrixSelecionada[i,j] <- 1
}
}
}
> g <- as(matrixSelecionada, "graphNEL")
> g
A graphNEL graph with directed edges
Number of Nodes = 56
Number of Edges = 1256
> glg <- getLargestSubgraph(g)
Error: .validateGraph(g) is not TRUE
But when I do validateGraph
> validGraph(g)
[1] TRUE
