sparsevctrs 0.2.0
CRAN release: 2025-01-22
New Functions
sparsity()has been added, allows sparsity calculations of data.frames, matrices, and sparse matrices. (#82)Utility function
has_sparse_elements()has been added. (#70)Helper function
sparse_dummy()has beenn added. (#49)Helper functions
sparse_mean(),sparse_var(),sparse_sd(),sparse_median()has been added. (#49)
Improvements
All sparse vector types now have a significant smaller base object size. (#67)
All coerce functions have received a
callargument. (#72)is_sparse_vector()has been rewritten for speed improvement. (#76)coerce_to_sparse_matrix()Now turns dense zeroes into sparse zeroes. (#77)
Bug Fixes
Fixed bug where
coerce_to_sparse_data_frame()andcoerce_to_sparse_tibble()didn’t work with matrices with fully sparse columns. (#69)Fixed bugs where
coerce_to_sparse_matrix()would error for completely sparse columns. (#77)
