Data frame to append to.

Examples

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

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

# 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
add_row(df, z = 10)
