r - Graph from adjacency list -

i have adjacency list , want visualize them , processing on it. there package efficiently. see there lot of graph packages confused among them. can me on this?

$`825` [1] 824  $`824` [1] 823  $`823` [1] 822  $`822` [1] 821  $`821` [1] 820 777  $`820` [1] 819 816 789 787 785 783  $`777` [1] 776 

above adjacency list. below graph want.

825  | 824  |          _______ 783 823        /  |        /________ 785 822      /  |      /__________ 787 821 -- 820  |      \__________ 789 777      \  |        \________ 816 776        \             \______ 819 

thanks.

 mylist <- list(2,c(1,3),c(2,4),c(3,1))  names(mylist) <- c(1,2,3,4)  # list   #make in igraph format  myadj <- stack(mylist)  #>    values ind #>     1      2   1 #>     2      1   2 #>     3      3   2 #>     4      2   3 #>     5      4   3 #>     6      3   4 #>     7      1   4   #plot  library(igraph)  g<-graph.data.frame(myadj)  plot(g)
