Looking at Outliers in R As I explained earlier, outliers can be dangerous for your data science activities because most statistical parameters such as mean, standard deviation and correlation are highly sensitive ...2. Remove Duplicate Column Names with unique(). The second method to remove duplicate column names is by using the unique() function.. In contrast to the duplicated() function, the unique() function returns a vector with distinct column names of a data frame.
