Columns can be split into multiple columns with the separate(column, into, sep="[\W_]+", remove=True, convert=False, extra='drop', fill='right') function. separate() takes a variety of arguments:column: the column to split. into: the names of the new columns. sep: either a regex ...
into: the names of the new columns. sep: either a regex string or integer positions to split the column on. remove: boolean indicating whether to remove the original column. convert: boolean indicating whether the new columns should be converted to the appropriate type (same as in spread abov...

return all rows from x, and all columns from x and y. Rows in x with no match in y will have NA values in the new columns. If there are multiple matches between x and y, all combinations of the matches are returned. # Combine the star_destroyer and millennium_falcon tablesmillennium_...
and handle default values for string columns. Hybrid min() and max() handle empty sets (#1481). n_distinct() uses multiple arguments for data frames (#1084), falls back to R evaluation when needed (#1657), reverting decision made in (#567). Passing no arguments gives an error (#1957...

all_equal() now reports multiple problems as a character vector (#1819, #2442). Factor levels must be equal for all_equal() (#2440, #2442). One of the two join suffixes can now be an empty string, dplyr no longer hangs (#2228, #2445). Data frame columns are rejected explicitly in...
