R Join without Duplicates Understanding the Problem When working with data from different datasets or tables, it’s common to need to merge the data together based on certain criteria. However, when one table has fewer observations than another table, this can lead to duplicate rows in the resulting merged table. In this case, we want to avoid these duplicates and instead replace them with NA values. The provided example uses two tables, tbl_df1 and tbl_df2, where tbl_df1 contains data for both years x and y.
