July 31, 2012

Version 0.2.0 of the recently introduced RcppCNPy package for reading/writing NumPy data in R arrived on CRAN earlier today.

The main change are the added ability to also write gzip-ed npy files, to suppress an automatic transposition as well as the correction of one memory leak on data read.

The NEWS file entry is below:

Changes in version 0.2.0 (2012-07-30)

  • Support for writing of gzip-ed npy files has been added.

  • A new option dotranspose has been added to npyLoad() to support data sets that do not need to be transposed to be used in R.

  • A memory leak in reading files has been corrected.

CRANberries also provides a diffstat report for 0.2.0 relative to 0.1.0. As always, feedback is welcome and the rcpp-devel mailing list off the R-Forge page for Rcpp is the best place to start a discussion.
