surveytidy 0.6.0

New features

survey_collection support

Collection-aware methods for all standard dplyr/tidyr verbs are now
dispatched per-survey when called on a survey_collection. The result
is a new survey_collection whose @id, @if_missing_var, and
@groups properties are preserved.

• Data-masking verbs: filter(), filter_out(), mutate(), arrange()
• Tidyselect verbs: select(), relocate(), rename(), rename_with(), drop_na(), distinct(), rowwise()
• Grouping verbs: group_by(), ungroup(), group_vars(), is_rowwise()
• Slicing verbs: slice(), slice_head(), slice_tail(), slice_min(), slice_max(), slice_sample()
• Collapsing verbs: pull() (returns a vector via vctrs::vec_c()), glimpse() (default mode binds members; .by_survey = TRUE per-member)

The .if_missing_var argument on each verb ("error" (default) or "skip") lets you override the collection's stored missing-variable behaviour for a single call. Skipped surveys are reported via the typed message class surveytidy_message_collection_skipped_surveys.

The 6 join verbs (left_join(), right_join(), inner_join(), full_join(), semi_join(), anti_join()) error with surveytidy_error_collection_verb_unsupported when called on a survey_collection. Apply joins inside a per-survey pipeline before constructing the collection.

surveycore re-exports

library(surveytidy) is now sufficient to use the collection construction and setter API. The following surveycore symbols are re-exported:

• as_survey_collection()
• set_collection_id()
• set_collection_if_missing_var()
• add_survey()
• remove_survey()

Bug fixes

• replace_when() and replace_values() no longer retain stale value labels for values absent from the recoded result. Previously, collapsing or replacing values left label entries (e.g. "High" = 4) attached to a vector that contained no such values. User-supplied .value_labels are always preserved.

New error / warning / message classes

• surveytidy_error_collection_verb_emptied
• surveytidy_error_collection_verb_failed
• surveytidy_error_collection_by_unsupported
• surveytidy_error_collection_select_group_removed
• surveytidy_error_collection_rename_group_partial
• surveytidy_error_collection_slice_zero
• surveytidy_error_collection_pull_incompatible_types
• surveytidy_error_collection_glimpse_id_collision
• surveytidy_error_collection_verb_unsupported
• surveytidy_warning_collection_rowwise_mixed
• surveytidy_message_collection_skipped_surveys

Dependency changes

• Adds vctrs (>= 0.6.0) to Imports (used by pull.survey_collection and glimpse.survey_collection).
• Bumps surveycore minimum-version pin to (>= 0.8.2).
