You might take a look at the 'graph' and 'RBGL' packages (both are
Bioconductor packages).  

There is a graphAM class that can be initialized with an adjacency
matrix.  Most functions in RBGL take either any graph instance or a
graphNEL.  So you might have (approx. and untested):

library(graph)
library(RBGL)
myAdjMat
g1 = new("graphAM", myAdjMat)
g2 = as(g1, "graphNEL")
## call some RBGL function on g2
