Bind multiple data frames by row


Bind any number of data frames by row, making a longer result. This is similar to, dfs), but the output will contain all columns that appear in any of the inputs.


bind_rows(..., .id = NULL)



Data frames to combine. Each argument can either be a data frame, a list that could be a data frame, or a list of data frames. Columns are matched by name, and any missing columns will be filled with NA.


The name of an optional identifier column. Provide a string to create an output column that identifies each input. The column will use names if available, otherwise it will use positions.


A data frame the same type as the first element of ....


df1 <- tibble(x = 1:2, y = letters[1:2])
df2 <- tibble(x = 4:5, z = 1:2)

# You can supply individual data frames as arguments:
bind_rows(df1, df2)

# Or a list of data frames:
bind_rows(list(df1, df2))

# When you supply a column name with the `.id` argument, a new
# column is created to link each row to its original data frame
bind_rows(list(df1, df2), .id = "id")
bind_rows(list(a = df1, b = df2), .id = "id")
