Reload package-built experimental t-SNE affinities

Validates every CSR row and checks file contents against the manifest written by massive_tsne_affinities(). A generic external CSR graph cannot be treated as a package-built t-SNE affinity graph.

Usage

massive_affinity_graph(prefix, n_vertices, access = c("stream", "mmap"))

Arguments

prefix

Prefix of the existing CSR file triple.

n_vertices

Number of vertices; currently at most 2^31 - 1.

access

Sequential file reads or memory-mapped access for later bounded edge reads. Import validation always streams.

Value

A verified fastEmbedR_massive_graph descriptor.
