[R] [R-pkgs] The 'atsd' package released.

[mikhail.zvagelsky at axibase.com]

Dear R users,

I would like to announce the release of the "atsd" R package on CRAN, 
which offers functions for retrieving time-series and related meta-data 
such as entities, metrics, and tags from Axibase Time Series Database (ATSD).

http://cran.r-project.org/web/packages/atsd/index.html

ATSD runs on top of HBase to collect, analyze and visualize time series data at scale. 
ATSD capabilities include optimized storage schema, built-in rule engine, forecasting 
algorithms include Holt-Winters, ARIMA and graphics designed for high-frequency data. 
Primary use case: IT infrastructure resource monitoring.

The main focus of "atsd" R package is to simplify data retrieval. This package eliminates 
the need to manually retrieve historical data and forecasts, before any advanced analysis 
is executed. The "atsd" R package fetches data and tags from ATSD, and converts them into 
a data frame object which can be readily consumed by other R packages.

Key supported functions for retrieving data:

· query() -- get historical data and forecasts from ATSD. 
             This function supports aggregation: COUNT, MIN, MAX, AVG, WAvg, WTAvg, SUM, 
             PERCENTILES (50%, 75%, 90%, 95%, 99%, 99.5%, 99.9%), STANDARD_DEVIATION. 
             The function also supports interpolation: NONE, STEP, LINEAR.

· get_metrics() -- get information about the metrics collected by ATSD.

· get_entities() -- get information about the entities collected by ATSD.

· to_zoo() -- converts a time-series data frame to 'zoo' object for manipulating irregular 
              time-series with built-in functions in zoo package.
