This function removes all duplicate columns where TADA has created a new column with a TADA prefix. It retains all TADA prefixed columns as well as other original fields that are either required by other TADA functions or are commonly used filters. Using this function allows the user to accept all TADA created changes and reduce the size of the data set before using TADA mapping or data visualization features in the TADA package or Shiny app.
Value
A dataframe containing all required fields for use with TADA as well as fields commonly used for filtering.
Examples
data(Data_Nutrients_UT)
reducedcols_Data_Nutrients_UT <- TADA_RetainRequired(Data_Nutrients_UT)
