Arguments

.data	Data frame to append to.

.before, .after	One-based row index where to add the new rows, default: after last row

Examples

# add_row ---------------------------------
df <- tibble(x = 1:3, y = 3:1)

add_row(df, x = 4, y = 0)

# You can specify where to add the new rows
add_row(df, x = 4, y = 0, .before = 2)

# You can supply vectors, to add multiple rows (this isn't
# recommended because it's a bit hard to read)
add_row(df, x = 4:5, y = 0:-1)

# Absent variables get missing values
add_row(df, x = 4)

# You can't create new variables
## Not run: 
add_row(df, z = 10)

## End(Not run)
