TADA_AutoClean

Source: R/Utilities.R
TADA_AutoClean.Rd

This function performs the following tasks:

  1. Creates new columns with the TADA prefix "TADA." and capitalizes all letters within them so that they're interoperable with the WQX validation reference tables and to reduce issues with case-sensitivity when joining data: CharacteristicName, ResultSampleFractionText, MethodSpeciationName, ResultMeasure.MeasureUnitCode, ActivityMediaName, and DetectionQuantitationLimitMeasure.MeasureUnitCode.

  2. This function runs "TADA_ConvertSpecialChars" on these columns: ResultMeasureValue and DetectionQuantitationLimitMeasure.MeasureValue. Creates new versions of these columns with the TADA prefix "TADA."

  3. Converts the column type of LatitudeMeasure and LongitudeMeasure to numeric (double) and creates new columns with the “TADA” prefix.

  4. Replace meters" with “m” in the following columns: TADA.ResultMeasure.MeasureUnitCode, ActivityDepthHeightMeasure.MeasureUnitCode, ActivityTopDepthHeightMeasure.MeasureUnitCode, ActivityBottomDepthHeightMeasure.MeasureUnitCode, and ResultDepthHeightMeasure.MeasureUnitCode.

  5. Runs TADA_SubstituteDeprecatedChars to replace deprecated characteristic names based on Water Quality Exchange (WQX) Characteristic domain table.

  6. Runs TADA_ConvertResultUnits to harmonize result and detection limit units to WQX and TADA or user supplied target units. Enter ?TADA_ConvertResultUnits and ?TADA_CreateUnitRef() into the console for more details.

  7. Runs TADA_ConvertDepthUnits to convert the depth units to meters on the following columns: ResultDepthHeightMeasure.MeasureValue, ActivityDepthHeightMeasure.MeasureValue, ActivityTopDepthHeightMeasure.MeasureValue, and ActivityBottomDepthHeightMeasure.MeasureValue, and add new columns with the “TADA” prefix.

  8. Runs TADA_CreateComparableID to create a comparable data group by concatenating TADA.CharacteristicName, TADA.ResultSampleFractionText, TADA.MethodSpeciationName, and TADA.ResultMeasure.MeasureUnitCode.

Usage

TADA_AutoClean(.data)

Arguments

.data

TADA dataframe

Value

Input dataframe with several added TADA-specific columns, including:

TADA.ActivityMediaName (character) TADA.ResultSampleFractionText (character) TADA.CharacteristicName (character) TADA.MethodSpeciationName (character) TADA.ComparableDataIdentifier (character) TADA.ResultMeasureValue (numeric) TADA.ResultMeasureValueDataTypes.Flag (character) TADA.ResultMeasure.MeasureUnitCode (character) TADA.WQXResultUnitConversion (character) TADA.DetectionQuantitationLimitMeasure.MeasureValue (numeric) TADA.DetectionQuantitationLimitMeasure.MeasureValueDataTypes.Flag (character) TADA.DetectionQuantitationLimitMeasure.MeasureUnitCode (character) TADA.ResultDepthHeightMeasure.MeasureValue (numeric) TADA.ResultDepthHeightMeasure.MeasureValueDataTypes.Flag (character) TADA.ResultDepthHeightMeasure.MeasureUnitCode (character) TADA.ActivityDepthHeightMeasure.MeasureValue (numeric) TADA.ActivityDepthHeightMeasure.MeasureValueDataTypes.Flag (character) TADA.ActivityDepthHeightMeasure.MeasureUnitCode (character) TADA.ActivityTopDepthHeightMeasure.MeasureValue (numeric) TADA.ActivityTopDepthHeightMeasure.MeasureValueDataTypes.Flag (character) TADA.ActivityTopDepthHeightMeasure.MeasureUnitCode (character) TADA.ActivityBottomDepthHeightMeasure.MeasureValue (numeric) TADA.ActivityBottomDepthHeightMeasure.MeasureValueDataTypes.Flag (character) TADA.ActivityBottomDepthHeightMeasure.MeasureUnitCode (character) TADA.LatitudeMeasure (numeric) TADA.LongitudeMeasure (numeric)

Please note that the number of TADA-specific depth columns in the returned dataframe depends upon the number of depth columns with one or more results populated with a numeric value. If all depth columns contain only NA's, no conversion is necessary and no TADA depth columns are created.

Details

Original columns are not changed: new columns are added to the end of the dataframe with the prefix "TADA.". TADA_AutoClean can be run as a stand alone function but is primarily used by the TADA_dataRetrieval function.
