data.sketches 0.1.0

• Initial release. Provides an R interface to the Apache DataSketches C++ library:
  • Quantile sketches: kll_doubles(), kll_floats(), req(), and tdigest_double().
  • Cardinality sketches: hll(), cpc(), and theta() (with set operations).
  • Frequency sketches: frequent_items() and count_min().
  • Tuple sketches: array_of_doubles() (with set operations).
  • Sampling sketches: varopt() and ebpps().
  • Filters: bloom_filter().
  All sketches provide $update(), $merge(), $summary(), $inspect(), and native $serialize() / bytes = round-tripping, plus format(), print(), as.character(), and summary() methods.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
