In sparsevctrs: Sparse Vectors for Use in Data Frames

sparsevctrs 0.3.4

Bug Fixes

• Fixed bug where sparse_multiplication() had a stack imbalence when returning all 0s. (#113)

• Fixed bug where sparse_is_na(type = "integer") would error on character vectors. (#116)

sparsevctrs 0.3.3

Bug Fixes

• Fixed bug where coerce_to_sparse_matrix() would sometimes error if input had NA values. (#109)

sparsevctrs 0.3.2

Bug Fixes

• Fixed bug where sparsity() error on numeric vectors with classes. (#106)

sparsevctrs 0.3.1

• Fixed bug where sparse multiplication caused undefined behaviour. ($103)

sparsevctrs 0.3.0

New Functions

• Adding the scalar arithmatic functions sparse_division_scalar(), sparse_multiplication_scalar(), sparse_addition_scalar(), sparse_subtraction_scalar(). (#87)

• Adding the arithmatic function sparse_multiplication(). (#93)

• Helper function sparse_lag() bas been added. (#99)

• Helper function sparse_sqrt() has been added. (#90)

• Helper function sparse_replace_na() has been added. (#91)

• Helper functions sparse_is_na() and sparse_which_na() have been added. (#92)

Improvements

• Adding wts argument to sparse_mean(). (#95)

Bug Fixes

• Fixed bug in coerce_to_sparse_data_frame() and coerce_to_sparse_tibble() where they didn't work with ngCMatrix. (#89)

sparsevctrs 0.2.0

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 call argument. (#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() and coerce_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)

sparsevctrs 0.1.0

• Initial CRAN submission.
