Pair Results for Numeric Criteria Calculation (UNDER ACTIVE DEVELOPMENT)

This function pairs TADA results with results from specified characteristics from the same TADA.MonitoringLocation within a user-specified time window to facilitate the calculation of numeric criteria. The columns created by TADA_AutoClean are required to run this function. If they are not present in the data frame, the function will stop and print an error message.

Usage

TADA_PairForCriteriaCalc(.data, ref = "null", hours_range = 4)

Arguments

.data: TADA dataframe
ref: Write description of what columns need to be in this ref or null option
hours_range: Numeric argument. The time difference allowed between the paired characteristic and the result.

Value

A TADA data frame with six additional columns added for each pairing group specified in the pairing ref.

Details

Users can provide a pairing reference file (can be created using TADA_CreatePairRef) to specify which combinations of TADA.CharacteristicName, TADA.ResultMeasure.MeasureUnit, TADA.MethodSpeciationName, and TADA.ResultSampleFractionText should be used for hardness, pH, temperature, salinity, chloride or other user-defined groups. If no ref is specified, all possible combinations for hardness, pH, temperature, salinity and chloride will be used. It is highly recommended that users perform all unit conversion and synonym harmonization before using TADA_PairForCriteriaCalc.

Examples

if (FALSE) { # \dontrun{
AL_df <- TADA_DataRetrieval(
  startDate = "2010-11-30",
  endDate = "2010-12-01",
  statecode = "AL",
  ask = FALSE
)

AL_PairRef <- TADA_PairForCriteriaCalc(AL_df)
} # }
