Differential privacy

Exact discrete Laplace noise for counts and histograms, the analytic Gaussian mechanism for means, and a privacy budget the releases are charged against.

dplapcnt(): Differentially-private count via the discrete Laplace mechanism
dplaphist(): Differentially-private histogram via the discrete Laplace mechanism
dpgmean(): Differentially-private mean via the analytic Gaussian mechanism
dpbudget(): A privacy budget that DP releases are charged against
dpspent(): What a privacy budget has spent

k-anonymity and l-diversity

Checks of a table’s quasi-identifier classes before release.

kanonvrf(): k-anonymity verification
ldivvrf(): l-diversity verification

Cell suppression

Primary and complementary suppression of small cells, audited for exact recovery from the margins.

cellsupp(): Cell suppression with complementary suppression and a recoverability audit

Sample data objects

Small documented data frames bundled for examples and tests (lazy-loaded via data()).

arrest_sample: Chicago arrests sample

International datasets

Non-Canadian tables in the bundled store, reached by slug through mdload().

rmoriedata-victoria: Victorian crime statistics (Crime Statistics Agency Victoria)

Hosted tables

Curated tables served at data.rmorie.com, checked against the manifest’s SHA-256.
