R Question

I have a unconnected graph and I want to convert each component to a independent graph. This is an example, I have wrote which I couldn't reach to the result:

`gr<- graph( edges=c(1,2, 2,3,3, 1,4, 5), n=5, directed=F )`

is.connected(gr)

cl <- clusters(gr)

f<-induced.subgraph(gr1,which(cl$membership == which.max(cl$csize)))

sapply(gr, function(f) f)

Any idea to it?

```
gr <- graph( edges = c(1,2, 2,3, 3,1, 4,5), n = 5, directed = F)
is.connected(gr)
cl <- clusters(gr)
graph_splitting <- function(k, gr, cl = clusters(gr)){
induced.subgraph(gr, cl$membership == k)
}
sapply(1:max(cl$membership), graph_splitting, gr = gr, cl = cl, simplify = FALSE)
```
