Dplyr select rows by value. This is similar to unique. table. pick() returns a data frame containing the selected columns for the current group. select: the first argument is the data frame; the second argument is the names of the columns we want selected from it.

The filter() function is used to subset a data frame, retaining all rows that satisfy your conditions.
