Nests data set in preparation for calibration calculations. Use the
group_by parameter to group analyses as appropriate for calibration. Use iso_get_calibration_data to easily pull out columns from the nested data frame in
all_data at any point before, during or after calibration.
iso_prepare_for_calibration(dt, group_by = NULL, nest_existing_calibrations = FALSE, quiet = default(quiet))
what to group by for indidual calibration calculations (use c(...) to select multiple) - set
whether to nest existing calibrations. This is usually not necessary and only leads to larger data objects. By default, existing calibrations are therefore never included in the nested data set.
