[Rcpp-devel] efficient ingestion of "sparse csv" (Vincent Carey)

[Peter Hickey]

Hi Vince,

Aaron Lun (CC-ed) has written scuttle::readSparseCounts() for this purpose.
You may have already seen it since it's in BioC.
It's written in R rather than C++ but I imagine it's pretty efficient
since, well, it's written by Aaron
(https://github.com/LTLA/scuttle/blob/master/R/readSparseCounts.R).

Cheers,
Pete
