freeze {tframe} | R Documentation

## Get fixed data snapshot

### Description

Generic method. See specific methods for details.

### Usage

        freeze(data, ...)
        ## Default S3 method:
        freeze(data, ...)

### Arguments

`data` | A data source description.
`...` | Additional arguments for specific methods.

### Details

This function extracts data from a database (for example using the TS PADI programs are available at www.bank-banque-canada.ca/pgilbert). This method is generic. The function logically belongs with the tfpadi functions in the dsepadi package but the generic and default are included here since they are required in many functions whereas the database interface has much more limited use. Typically the argument data is a tfPADIdata or TSPADIdata object identifying the source of the data. See help for tfPADIdata and TSPADIdata. The default method usually just returns its argument, so freeze has no effect. This way freeze can be used to write functions which will take a snapshot from the database when they execute or will work with an already fixed copy of data if that is what is supplied. The default does allow for a character argument, in which case it is used to construct a tfPADIdata object using server="ets", then freeze that object. This allows for a simple syntax to grab a series from the database. The server="ets" is for convenience at the Bank of Canada and another default server might be more convenient elsewhere.
