Changes in version 2.0.0 o Converted beachmat into a header-only library to simplify linking, avoid ABI incompatibilities. o Minor API change for external native support to avoid using C++ classes with C-style linkage. Changes in version 1.4.0 o Removed native support for RleMatrix and packed symmetric matrices. o Added multi-row/column getters. o Added mechanism for native support of arbitrary developer-defined matrices. o Switched to row/colGrid() for defining chunks in unsupported matrices. Changes in version 1.2.0 o Changed environment variable to BEACHMAT_RPATH for consistency with other packages. o Added native support for transposition and subsetting in DelayedMatrix objects. o Added support for chunk-by-chunk realization of otherwise unsupported matrices, including DelayedMatrix objects with other delayed operations. o Added the get_const_col_indexed() method for input matrices, especially fast for sparse representations. o Added the set_col_indexed() and set_row_indexed() methods for output matrices. o Updated vignettes and expanded the test suite. Changes in version 1.0.0 o New package beachmat, which provides a C++ API for handling various R matrix types.
