Validate Multi-Stem Grouping (Internal)

dot-validate_multi_stem_grouping.Rd

Checks the multi_tiges_id column, which holds the tag of the main stem a secondary stem belongs to. It is a staging column: the import resolves it to data_individuals.stem_grouping, which stores the parent's id_n. Anything that cannot be resolved becomes a silently missing grouping after the insert, so it is checked beforehand.

Usage

.validate_multi_stem_grouping(data, con)

Arguments

data

Individuals data frame with plot_name, tag and multi_tiges_id

con

Database connection

Value

List with errors and warnings

Details

Checks performed, mirroring the Feature Wizard's multi-stem step:

  • values that are not a tag number (error)

  • a stem pointing at itself (error)

  • a parent tag absent from both the import and the plot in the database (error)

  • a parent that is itself a secondary stem, which would chain the grouping instead of pointing at the main stem (error)

  • members of a group carrying different idtax_n (warning)

  • a parent that already carries a grouping in the database (warning)
