Dear Peter Ehlers,

Thanks. 

In decompose help page of 'R' It's clearly mentioned that the output of decompose command is a separate graph for each component . 

It is true that, Variable in which  I stored my output is not a graph object. I tried the following command also - To directly save the output as a file. 

wri write.graph ("F://new", "pajek") <-      decompose.graph(g,  mode="weak", max.comps=NA, 
min.vertices= 20)



But even that doesn't work 


Is there a way in which I could convert my output to a graph ?

Regards
Chakri

Sure: compo is not an igraph object; it's a list as

class(compo) or reading the help page for decompose.graph

would tell you.
