Dplyr Package | Generate data summary using group_by ( ) and summarise ( ) functions
dplyr package provides the group_by ( ) function to group data based on specific variables and the summarize ( ) function to calculate summary statistics for each group.
group_by ( ) function lets you group data by one or more variables. By itself, it may not seem very useful, but it’s great when you start manipulating and summarizing data. That’s because many of the functions applied to data after you use group_by are done group-wise.
summarise ( ) function generates the data summary using various statistical functions. Useful summary functions such as min ( ), max ( ), median ( ), sd ( ) etc. are used to get insights on central tendency of the data-set.
