0.4-0
MAJOR CHANGES
- getSymbols now uses parent.frame() when auto.assign=TRUE. This
will cause slightly different behavior than previous versions
using .GlobalEnv, but is more functional in design.
- getSymbols now allows for env=NULL, which will behave
as if auto.assign=FALSE is set.
- Upcoming changes for version 0.5-0 will include deprecating
auto assignment from within getSymbols calls. This will instead
be moved to the loadSymbols function, to better match get/load
behaviors in base R. For the transition, auto.assign will be
available to force pre 0.5-0 behaviors, but will be discouraged.
The env= arg will be used for multiple symbol assigns.
0.3-7
- addTA now handles logical vectors or logical xtsible objects
by drawing bands on chart window
- addTA can now draw on or under any window via 'on=' arg
- chartSeries now cleanly handles series without volume automatically
- addVo has new log.scale option
0.3-6
MODIFICATIONS
- Delt (and functions that call) now defaults
to 'arithmetic' (discrete) calculations vs. the previous behavior
of 'log' (continuous) calculation. This is more inline with
expected behavior
-
NEW FUNCTIONALITY
- addTA and newTA allow for dynamic indicator additions with little coding
0.3-2
BUG FIXES
- matched broken TTR calls, aligned arguments between packages
- 'name' of chart was being evaluated somewhere in the process,
resulting in the object becoming a string. Fixed in this release.
MODIFICATIONS
- continuing the move of time-series functionality to the 'xts' package
- added new TTR functions to addTA.
- added underlay charting to main area (BBands) as well as much
more advanced shading and labeling.
- chartSeries converts incoming 'x' argument to xts object for
more universal handling. Not fully sorted out - but better than
before.
- new subset argument to allow for xts-style subsetting
NEW FUNCTIONALITY
- new TTR functions - ATR, CCI, CMF, CMO, DPO, Lines, Momentum, TRIX
0.3-1 ***********************************************************************
BUG FIXES
- new depends - on CRAN and R-Forge package xts for time-series handling internally
- options.expiry and futures.expiry now use universal %w to check weekdays
- Rmetrics change resulted in as.timeSeries moving to fSeries. New suggest and assoc. changes
MODIFICATIONS
- Added ability to plot series with missing values (like those in a 'ts' series)
Volume with missing obs. is still broken - to be fixed in 0.3-2
0.3-0 **********************************************************************
BUG FIXES
- Fixed factor bug in getSymbols.FRED. Thanks to Josh Ulrich
- Fixed bug in [.quantmod.OHLC method when i/j was missing,
also now returns quantmod.OHLC object consistently
MODIFICATIONS
- Added high frequency data handling - to.minutes, to.hourly,
to.daily. Additional work done to accomodate within rest of
framework
- getSymbols downloads now to temp file - instead of directly to
memory. Fixed R issue in certain Windows installations
- getSymbols now returns a character array of symbol names
written to environment.
- getSymbols includes new arg - auto.assign. If set to FALSE
will behave like standard R functions and simply return
loaded object. Requires user assignment via '<-'
- Better handling of timeSeries, ts, its within entire package
NEW FUNCTIONALITY
- chartSeries rewrite. Now manages charting with S4 objects
stored quietly in memory. Allowing for dynamic redraws used
in applying technical indicators and overlays
- addTA functions. New charting tools to add technicals to
charts dynamically. More on the way
- listTA, setTA, unsetTA to handle default TA args
- chartTheme function to customize chart 'look'
- last/first functions now take character strings to describe
in words the subsetting to do. Also negative value support
for opposite behavior. Additional _keep_ arg will assign
removed data to an attribute _keep_ with the object
- getSymbols.SQLite support. Still very clunky - though that is SQLite.
- getFX and getMetals for direct download of those types
- getQuote downloads Last,Change,Open,High,Low,Volume from Yahoo
- added documentation and fixed documentation
