Create a QWAdata object

The S3 class QWAdata holds the quantitative wood anatomy (QWA) measurements data produced from ROXAS output files, organised into two components:

Usage

QWAdata(cells = NULL, rings = NULL)

as_QWAdata(x)

Arguments

cells

Data frame with cell-level measurements (optional).

rings

Data frame with ring-level measurements and flags (optional).

x

A named list with any subset of the QWAdata components.

Value

An object of class QWAdata.

Details

• $cells: cell-level measurements (one row per cell).

• $rings: ring-level measurements, and possibly also quality flags (one row per annual ring per image).

At least one component must be provided. The typical workflow builds a QWAdata object incrementally using collect_raw_data(), complete_QWAdata(), and check_QWAdata(). Metadata is kept separately as a QWAmetadata or QWAimages object. Radial profiles are computed separately as QWAprofile objects using calculate_sector_profiles() or calculate_band_profiles().
