Description This is a convenient way to add one or more rows of data to an existing data frame. See tribble () for an easy way to create an complete data frame row-by-row. Use tibble_row () to ensure that the new data has only one row.
2.3.1 dplyr::all_equal(). dplyr::all_equal(target, current) compare if current and target are identical ,and it could only compares 2 data frames at the same time, with several other arguments:

First, we added a single empty column by simply assigning NA to it. Second, we then used the function add_column () with the new column name as an argument and NA as input. tibble() constructs a data frame. It is used like base::data.frame(), but with a couple notable differences: The returned data frame has the class tbl_df, in addition to data.frame. This allows so-called "tibbles" to exhibit some special behaviour, such as enhanced printing. Tibbles are fully described in tbl_df. Tibbles are the modern reimagination of data frames and share many commonalities with their ancestors.
2020-03-25 · “A tibble, or tbl_df, is a modern reimagining of the data.frame, keeping what time has proven to be effective, and throwing out what is not. Tibbles are data.frames that are lazy and surly: they do less (i.e. they don’t change variable names or types, and don’t do partial matching) and complain more (e.g. when a variable does not exist).
There are three ways to form a tibble. It pretty much acts as your friendly old pal data.frame () does. Just like standard data frames, we can create tibbles, coerce objects into tibbles and import data sets into R as a tibble.

Using as_tibble()for vectors is superseded as of version 3.0.0, prefer the more expressive as_tibble_row() and as_tibble_col() variants for new code. See Also tibble()constructs a tibble from individual columns. enframe()converts a named vector to a tib-ble with a column of names and column of values. Use relocate() to change column positions, using the same syntax as select() to make it easy to move blocks of columns at once. I need to send the data I have in a tibble to a partner in an excel or csv file format.
