proxyC 0.4.2

New features and improvements

  • Reduce the overhead for dense similarity matrices by improving rounding numbers and conversion to Rcpp vectors.
  • Return a dense matrix if sparse = FALSE to save space in RAM.

proxyC 0.4.1

Bug fixes

  • Make detection of Intel oneAPI Threads Building Blocks (TBB) library more reliable.

proxyC 0.4.0

New features and improvements

  • Use more recent Intel oneAPI Threads Building Blocks (TBB) library to improve the stability in parallel computing.
  • Add options(proxyC.threads) to control the number of threads in parallel computing (but RCPP_PARALLEL_NUM_THREADS still has effect).

New system requirements

  • The RcppParallel package is no longer required as the TBB library in the operating system (Linux and MacOS) or Rtools (Windows) is used.
  • Linux and MacOS must have the TBB library to enable parallel computing before installing this package from the source.

proxyC 0.3.4

New features and improvements

  • Add "fjaccard" to simil() for Fuzzy Jaccard similarity (#42).

proxyC 0.3.3

New features and improvements

  • Explicitly setting use_nan = FALSE will suppress warnings in simil() and dist().
  • Add vignettes to explain how the similarity and distance measures are computed.

proxyC 0.3.2

Bug fixes

  • Make further changes for Matrix v1.4-2.

proxyC 0.3.1

New features and improvements

  • Add "jensen" to dist() for Jensen-Shannon divergence as a symmetric version of Kullback-Leibler divergence.
  • Change how x and y are coerced to dgCMatrix for Matrix v1.4-2.

proxyC 0.3.0

New features and improvements

  • Add "jeffreys" to dist() for Jeffreys divergence. It is a symmetric version of Kullback-Leibler divergence (#31).

proxyC 0.2.4

New features and improvements

  • rowSds(), colSds(), rowZeros() and colZeros() return row or column names. They also work with both dense and sparse matrices (#28).

proxyC 0.2.3

Bug fixes

  • Change "hamman" to "hamann" in simil() to correct misspelling (#26).

proxyC 0.2.2

New features

  • simil() and dist() work with both dense and sparse matrices.
  • use_nan = TRUE can be used not only for correlation but for all the distance and similarity measures.

proxyC 0.2.1

New features

  • Computing the correlation similarity on vectors with a standard deviation will generate a zero correlation and a warning. The warning can be turned off by setting use_nan = TRUE, in which case the computed correlation similarity will be NaN instead (#21).

Bug fixes

  • Fixed infinite values being returned by the correlation similarity (#20).

proxyC 0.2.0

New features

  • Added a diag argument to compute similarity/distance only for corresponding rows or columns (#13).
  • Added a smooth parameter to chisquared and kullback leibler distances to solve negative values in sparse matrices (#15).
  • Added the hamming distance (#18)

Bug fixes

  • Fixed the chi-squared distance to match stats::chisq.test() (#14).
  • Fixed a bug in pairwise similarity/distance computation when drop0 = TRUE (#17).

proxyC 0.1.5

New features

  • Add the drop0 argument to address the floating point precision issue (#10).

Bug fixes

  • The digit argument is now passed to dist() (#11).

proxyC 0.1.4

New features

  • Add rowSds(), colSds(), rowZeros() and colZeros() (#9).

proxyC 0.1.3

Bug fixes

  • No longer assumes symmetry of resulting matrix when x != y (#4).

New features

  • Add the digits argument to correct rounding errors in C++ (#5).
