Prune a datras_raw object following the FishGlob workflow

Reduce a datras_raw / DATRASraw object to the components and columns needed for the FishGlob workflow.

Usage

prune_fishglob(x)

Arguments

x

A datras_raw object.

Value

A pruned datras_raw object following the FishGlob workflow.

Details

This function removes the CA table entirely and retains only a selected subset of columns in the HH and HL tables. It is mainly intended to reduce memory use when preparing data in a format consistent with the FishGlob data workflow.

The FishGlob workflow does not require the full DATRAS object. In particular, the CA table is discarded and only a reduced set of variables is kept from the HH and HL tables.

This can substantially reduce memory use when working with large survey data sets.
