Once a data frame has been wrapped by tibble/tbl_df, is there a command to view the whole data frame though (all the rows and columns of the data frame)?. The edges followed from one vertex to another are called a path. We can work around this by combining both calls to across() into a single expression that returns a tibble: Alternatively we could reorganize results with relocate(): If you need to, you can access the name of the current column inside by calling cur_column(). For example, a for loop can be inside a while loop or vice versa.
