Well, thanks a lot for the replies. At the end I was able to install igraph.
Now. the problem is that I have a *.rdata file. It contains an object "g2". It is a list with 9 elements. > str(g2) List of 9 $ : num 7200 $ : logi FALSE $ : num [1:123504] 1 2 3 4 5 6 7 8 9 10 ... $ : num [1:123504] 0 0 0 0 0 0 0 0 0 0 ... $ : num [1:123504] 0 1 2 3 4 5 6 7 8 9 ... $ : num [1:123504] 0 1 2 3 4 5 6 7 8 9 ... $ : num [1:7201] 0 0 1 2 3 4 5 6 7 8 ... $ : num [1:7201] 0 51 51 53 53 53 53 53 54 56 ... $ :List of 4 ..$ : num [1:2] 1 0 ..$ : Named list() ..$ : list() ..$ : list() - attr(*, "class")= chr "igraph" This object "g2" is an igraph. > is(g2) [1] "igraph" Now, how can I open this *.rdata file using igraph?? I am not able to find an appropriate command for it.
