lag_df

The <code>lag_df</code> function creates additional columns based on a list of column names
and lag sequences. This feature is beneficial for scenarios where you need
varying lag selections for certain columns, allowing flexibility in specifying
different lags for different columns or opting for no lag at all.

Interface for multiple data sources, such as the
`EDDS` API <https://evds2.tcmb.gov.tr/index.php?/evds/userDocs> of the
Central Bank of the Republic of Türkiye and the
`FRED` API <https://fred.stlouisfed.org/docs/api/fred/> of the Federal Reserve Bank.
Both data providers require API keys for access, which users can easily obtain
by creating accounts on their respective websites.
The package provides caching ability with the selection of periods to increase the
speed and efficiency of requests.
It combines datasets requested from different sources,
helping users when the data has common frequencies.
While combining data frames whenever possible, it also keeps all requested data
available as separate data frames to increase efficiency.
