mario.Database.add_extensions

Database.add_extensions(io, matrix, units, backup=True, inplace=True, calc_all=True, notes=None, EY=None)

Adding a new extension [Factor of production or Satellite account] to the database passing the coefficients or the absolute values.

Note

This function will delete all the exisiting scenarios and implement the new sets of the matrices in the baseline.

Parameters:

io (str, pd.DataFrame) – if the data is given from an excel file, is the path to the file else is a pd.DataFrame
matrix (str) –
defines where the new extension should be added to. The options are :
- ’v’ value added by coefficient
- ’V’ value added by absolute value
- ’e’ satellite account by coefficient
- ’E’ satellite account by absolute
units (pd.DataFrame) – a dataframe whose rows are the items to be added and single column which contains the units for every row
backup (boolean) – creates a backup of the last database to recover if needed
inplace (boolean) – if True, will change the database inplace otherwise will return a new object
calc_all (boolean) – if True, will calculate the main missing data
notes (list, Optional) – to add notes to the metadata
EY (pd.DataFrame, Optional) – In case that E,e are used as the matrix, EY can be updated too

Returns:
