pkgDepends to (recursively) find the the complete dependency graph of the packages on CRAN. This time, doing this for all almost 10,000 packages took too long,
so I used available.packages do get the one-step list of dependencies, build the (alsmost ) 10,000 x 10,000 adjacency matrix, and then used the SparseM packages to compute the matrix powers to get the complete dependency graph. Computing matrix powers without SparseM also proved to be infeasibly time consuming.
