Get time series matrix structure from a database
TSget(serIDs, con=options()$TSconnection, ...) ## S4 method for signature 'character, missing': TSget(serIDs, con=options()$TSconnection, ...) ## S4 method for signature 'character, ANY': TSget(serIDs, con=options()$TSconnection, ...)
con |
A database connection. |
serIDs |
identifiers for series to extract. |
... |
Arguments passed to TSget.SQL or other methods. |
These functions extracts data from
a database using a connection. This method is generic.
The argument serIDs
should give identifiers for the series to extract.
TSget
and other functions also provide a way to query a regularly
used database by setting the connection in options
using options(TSconnection=con)
, so then only the series identifiers
need to be specified in calls to TSget
.
If the database supports vintages or panels then it is also possible to set
defaults for these with, for example, options(TSvintage="current")
and
options(TSpanel="Canada")
. The default specification has to be supported
by the database for this to work.
The user can specify a default time series representation with
options(TSrepresentation="something")
, where "something" might
typically be "zoo".
If TSrepresentation
is not set with options()
and not specified
in the call then the ts representation is used for data from tables
"A", "Q", "M","S" and zoo
otherwise. See TSput
for a
list of the various tables. ONLY THIS DEFAULT IS WORKING AT PRESENT.
