Re: [igraph] Get communities with less than 8 nodes then remove isolates

[Benika H]

Hi again,

I've recently ran the following code.

c1 <- clusters(y)

c1$membership

layout <- layout.fruchterman.reingold(y)

x <- (which(c1$csize) < 8 & (c1$csize)> 1)

vertices <- which(c1$membership==x)

plot(subg,layout=layout[vertices])

When I do c1$csize, it tells me I should have 32 communities that fit that range in x.

However, it only plots 4 vertices.

Any ideas why???

It would still print the nodes outside that range. I think I just an error in my plot lines.

Thanks for checking. Hopefully, this is the solution.

Thanks everyone ,

What's wrong with my off list suggestion. Doesn't 

right_size <- which(sizes(wc) < 8 & sizes(wc) > 1)

subg <- induced.subgraph(y, which(membership(wc) %in% right_size))

work?

Hi,

I am trying to get all of the communities that have less than 8 nodes but more than 1 node.

I've tried many things thus far.

Immediate help is needed.

Here is what I'm trying now:

y <- graph.data.frame(t, directed=FALSE)

z <- graph.data.frame(u, directed=FALSE)

wc <- walktrap.community(y, weights = edgeList$Weight, steps=6, merges =TRUE, modularity = TRUE, membership = TRUE)

x <- which(sizes(wc) < 8  & sizes(wc) >1)

x

subg <-induced.subgraph(y,which(membership(wc) == x))

I've also tried the methods cliques, clusters and decompose.
