[Rcpp-devel] efficient ingestion of "sparse csv"

[Vincent Carey]

This problem has been discussed in various places but I don't
see a clear solution.  Certain applications are generating
large comma-delimited files with mostly zero entries.  The aim
is to ingest efficiently, converting to sparse representation
a record at a time.  Presumably a triplet format would be the
initial internal representation, with an aim to convert at
the end to Matrix dgCmatrix format.  Has anyone tackled this
in Rcpp or RcppArmadillo?
