iotables (version 0.9.3)

rows_add: Add conforming row(s)

Description

Add a conforming row, or elements of a conforming row to a names matrix.

Usage

rows_add(data_table, rows_to_add, row_names = NULL, empty_fill = 0)

Value

An extended data_table with the new row(s) binded.

Arguments

data_table

A symmetric input-output table, a use table, a margins or tax table retrieved by the iotable_get function.

rows_to_add

A data frame or a named numeric vector.

row_names

An optional name or vector of names for the key column. Defaults to NULL.

empty_fill

What should happen with missing column values? Defaults to 0. If you want to avoid division by zero, you may consider a very small value such as 0.000001.

Details

If you want to add a single row manually, you can input a named numeric vector or a data frame with a single row. For multiple rows, input them as wide form data frame (see examples.)
