Terribly-Simple Data Base for Time Series
Description
A terribly-simple data base for numeric
time series, written purely in R, so no external
database-software is needed. Series are stored in
plain-text files (the most-portable and enduring file
type) in CSV format. Timestamps are encoded using R's
native numeric representation for 'Date'/'POSIXct',
which makes them fast to parse, but keeps them
accessible with other software. The package provides
tools for saving and updating series in this
standardised format, for retrieving and joining data,
for summarising files and directories, and for
coercing series from and to other data types (such as
'zoo' series).
