A.6 Summarising Ranges

The summarise function will return a DataFrame because the information required to return a Ranges object is lost. It is often most useful to use summarise() in combination with the group_by() family of functions.

#> DataFrame with 2 rows and 2 columns
#>       query        gc
#>   <integer> <numeric>
#> 1         1  0.675555
#> 2         2  0.635795
