Create a QWAprofile object

QWAprofile is a subclass of data.frame that holds profiles of QWA measurements aggregated along the annual rings. Usually elements of the $profiles slot of a QWAdata object.

Usage

QWAprofile(data, profile_type = c("sector", "band"))

Arguments

data

A data frame containing the profile data. Must include at minimum columns identifying the image/ring (image_label, year) and the bin position.

profile_type

The binning scheme used: "sector" (relative position, default) or "band" (fixed-width distance bands).

Value

An object of class c("QWAprofile", "data.frame") with a profile_type attribute.

Details

Two profile types are supported, set via the profile_type attribute:

• "sector": bins defined by equal relative position sectors across the ring width (0–100%). calculate_sector_profiles()

• "band": bins defined by fixed-width distance bands in microns. calculate_band_profiles()
