dplyr: summarize

Показать описание

The summarize (aka summarise) function in dplyr lets you create summary statistics from the columns of a data frame. When run on an ungrouped data frame, a summary of a column should be a single value like the mean, median, mode, etc. We will learn how to generate summary statistics on subsets of the data using grouping in the next lesson.
