wts
argument to sparse_mean()
.
(#95)coerce_to_sparse_data_frame()
and
coerce_to_sparse_tibble()
where they didn’t work with
ngCMatrix. (#89)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_median()
has been added. (#49)
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)
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)
