Dear Parta Sarathi Das,

As far as I understand iGraph for R, iGraph changed it's definition in some version so there are two packages in R now: igraph0 which starts the counting with 0 and igraph which start the counting with 1.

Cheers,

Tim

Dear All
Suddenly im finding a silly error in igraph
and i am not able to understand why its showing so

*g <- graph( c(0,1, 1,2, 3,4, 5,6) )*

Error in graph(c(0, 1, 1, 2, 3, 4, 5, 6)) :
   At structure_generators.c:84 : Invalid (negative) vertex id, Invalid
vertex id

but if i put
  g <- graph( c(1,2, 3,4, 5,6) )
 > g
IGRAPH D--- 6 3 --
doesnot give any error
so far i know the vertices in igraph starts from 0.
I am using R version 2.15.3 and i graph version  0.6.5-2
