drv |
A SQLiteDriver. |
dbname |
A character string indicating a database name. |
con |
A database connection. |
serIDs |
identifiers for series to extract. |
x |
data series to put on the database, or a series identifier for TSdescription and TSdoc or, for print, a database connection as returned by TSconnect. |
TSrepresentation |
time series representation to use for the result. |
names |
Optional character vector to use for series names. |
tf |
Optional tframe to use for truncating data. (See tfwindow.) |
start |
Optional start date to use for truncating data. (See tfwindow.) |
end |
Optional end date to use for truncating data. (See tfwindow.) |
TSdescription |
TRUE or FALSE indicating whether description should be extracted |
TSdescription. |
Description to put on the database. |
TSdoc |
TRUE or FALSE indicating whether documentation should be extracted. |
TSdoc. |
Documentation to put on the database. |
TSlabel |
TRUE or FALSE indicating whether series label should be extracted. |
TSlabel. |
Short series label to put on the database. |
Table |
Database table indication (necessary if it cannot be determined automatically). |
vintage |
Vintage to be supplied (if supported by db). |
panel |
Panel to be supplied (if supported by db). |
... |
Arguments passed to other methods. |
