Clean a dataset by updating values below a certain minimum

clean.Min(bllFlowModel, ...)

# S3 method for BLLFlow
clean.Min(bllFlowModel, print = FALSE, ...)



The bllflow model we will clean


Arguments to the next method in the chain


A boolean which when set to TRUE prints logs of what the operation did


A bllflow named list whose dataset was cleaned

Methods (by class)

  • BLLFlow: Cleans the data using the min and outlier columns in the variables sheet of the MSW. Outlier method is applied on a row if any of the variable values for that row is less than the min value as specified in the variables sheet. Outlier checking for the column is not applied if min value is NA.

    Currently supported outlier methods are:
    1. Delete - Specified as 'delete' in MSW. Deletes the row from the data.
    number of deleted rows as well as their reason for deletion is stored in the metaData variable under the deletedRows name.
    2. Missing - Specified as 'missing' in MSW. Column value for that row which does not meet the criteria is set to NA.
    3. Not Applicable - TODO.
    4. Set to value - Specified as a number value in MSW. Column value for the row is set to the value specified in the outlier column.
