TSsql: Generic SQL helper functions for TSdbi SQL plugins
This package provides standard SQL query functions used by
SQL plugins packages for the TSdbi interface to time series databases.
It will mainly be used by other packages rather than directly by end
users. The one exception is the function TSquery which can be used to
construct a time series from a database containing observations over
time (e.g. balance statements for muliple years), but where the database
is not specifically designed to store time series (as with other
TSdbi SQL plugin packages).
Comprehensive examples of all the TS* packages is provided in the
vignette Guide.pdf with the TSdata package.
