I am learning to use dplyr and came across function slice. I tried to call it with and without explicit dplyr.
It works with explicit calling but gives error when called without dplyr. Can someone guide me what is the source of the error?
As far I know slice function is exclusive to dplyr or it belongs to some other package as well?
