Re: [igraph] MST

[Gábor Csárdi]

See write.graph() and the 'ncol' format, i.e. something like this:

library(igraph)

g <- read.graph("file.txt", format= "ncol")

mst <- minimum.spanning.tree(g)

write.graph(mst, file="output.txt", format="ncol")

Hello, 

I´m running the minimun.spanning.tree algorithm and I can´t see the output, how can I export the MST results into a .txt?

The imput txt is a three columns and n rows file, containing var1, var2 and edge, and i would need that the output has the same format. 

In previous versions this output was shown after entering the commands: 

library(igraph)

g <- read.graph("file.txt", format= "ncol")

minimum.spanning.tree(g)

I would thank if anyone can help
