filter_not_in: Title

In patdkeller/instR: Helper Functions for Institutional Research

Description

When you are looking to filter out items that appear in another dataframe, negating an %in% filter returns all records if you mistakenly refer to a column that does not exist in the comparison dataframe. This function protects against code running smoothly and the risk of missing the mistake by throwing an error.

Usage

filter_not_in(.data, OtherDf, columnInData, columnInOtherDf)

Arguments

.data	your dataframe
OtherDf	another data frame that you are comparing records with
columnInData	the column in your original dataframe that will be the basis of the filter
columnInOtherDf	the corresponding column found in the dataframe that you are comparing to
