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) )
dt | data table |
---|---|
group_by | what to group by for indidual calibration calculations (use c(...) to select multiple) - set |
nest_existing_calibrations | 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. |
quiet | whether to display (quiet=FALSE) or silence (quiet = TRUE) information messages. |
a nested data set with the group_by
columns out front and the remaining data in a new nested column named all_data
