Package: matrixStats
====================

Version: 0.5.0 [2012-04-16]
o Added weightedMad() from aroma.core v2.5.0.
o Added weightedMedian() from aroma.light v1.25.2.
o This package no longer depend on the aroma.light package for 
  any of its functions.
o Now this package only imports R.methodsS3, meaning it no 
  longer loads R.methodsS3 when it is loaded.


Version: 0.4.5 [2012-03-19]
o Updated the default argument 'centers' of rowMads()/colMads()
  to explicitly be rowMedians(x,...)/colMedians(x,...).  The
  default behavior has not changed.


Version: 0.4.4 [2012-03-05]
o BUG FIX: colMads() would return the incorrect estimates. This bug
  was introduced in matrixStats v0.4.0 (2011-11-11).
o ROBUSTNESS: Added system/redundancy tests for rowMads()/colMads().
o CRAN: Made the system tests "lighter" by default, but full tests 
  can still be run, cf. tests/*.R scripts.


Version: 0.4.3 [2011-12-11]
o BUG FIX: rowMedians(..., na.rm=TRUE) did not handle NaN (only NA).
  The reason for this was the the native code used ISNA() to test
  for NA and NaN, but it should have been ISNAN(), which is opposite
  to how is.na() and is.nan() at the R level work.  Added system
  tests for this case.


Version: 0.4.2 [2011-11-29]
o Added rowAvgsPerColSet() and colAvgsPerRowSet().


Version: 0.4.1 [2011-11-25]
o Added help pages with an example to rowIQRs() and colIQRs().
o Added example to rowQuantiles().
o BUG FIX: rowIQRs() and colIQRs() would return the 25% and the 75%
  quantiles, not the difference between them.  Thanks Pierre Neuvial
  at CNRS, Evry, France for the report.


Version: 0.4.0 [2011-11-11]
o Added rowRanks() and colRanks().  Thanks Hector Corrada Bravo
  (University of Maryland) and Harris Jaffee (John Hopkins).
o Dropped the previously introduced expansion of 'center' in rowMads()
  and colMads().  It added unnecessary overhead if not needed.


Version: 0.3.0 [2011-10-13]
o SPEEDUP/LESS MEMORY: colMedians(x) no longer uses rowMedians(t(x));
  instead there is now an optimized native-code implementation.
  Also, colMads() utilizes the new colMedians() directly.
  This improvement was kindly contributed by Harris Jaffee at
  Biostatistics of John Hopkins, USA.
o Added additional unit tests for colMedians() and rowMedians().


Version: 0.2.2 [2010-10-06]
o Now the result of {row|col}Quantiles() contains column names.


Version: 0.2.1 [2010-04-05]
o Added a startup message when package is loaded.
o CLEAN UP: Removed obsolete internal .First.lib() and .Last.lib().


Version: 0.2.0 [2010-03-30]
o DOCUMENTATION: Fixed some incorrect cross references.


Version: 0.1.9 [2010-02-03]
o BUG FIX: (col|row)WeightedMeans(..., na.rm=TRUE) would incorrectly 
  treat missing values as zeros.  Added corresponding redundancy tests
  (also for the median case).  Thanks Pierre Neuvial for reporting this.


Version: 0.1.8 [2009-11-13]
o BUG FIX: colRanges(x) would return a matrix of wrong dimension
  if 'x' did not have any missing values.  This would affect all
  functions relying on colRanges(), e.g. colMins() and colMaxs().
  Added a redundancy test for this case.  Thanks Pierre Neuvial
  at UC Berkeley for reporting this.
o BUG FIX: {col|row}Ranges() return a matrix with dimension names.


Version: 0.1.7 [2009-06-20]
WORKAROUND: Cannot use "%#x" in rowTabulates() when creating the column
names of the result matrix.  It gav an error OSX with R v2.9.0 devel
(2009-01-13 r47593b) current the OSX server at R-forge.


Version: 0.1.6 [2009-06-17]
o Updated the Rdoc example for rowWeightedMedians() to run conditionally 
  on aroma.light, which is only a suggested package - not a required one.
  This in order to prevent R CMD check to fail on CRAN, which prevents
  it for building binaries (as it currently happens on their OSX servers).


Version: 0.1.5 [2009-02-04]
o BUG FIX: For some errors in rowOrderStats(), the stack would not 
  become UNPROTECTED before calling error.
 

Version: 0.1.4 [2009-02-02]
o Added methods {col|row}Weighted{Mean|Median}s() for weighted averaging.
o Added more Rdoc comments.
o Package passes R CMD check flawlessly.


Version: 0.1.3 [2008-07-30]
o Added {col|row}Tabulates() for integer and raw matrices.
o BUG FIX: rowCollapse(x) was broken and returned the wrong elements.


Version: 0.1.2 [2008-04-13]
o Added {col|row}Collapse().
o Added varDiff(), sdDiff() and madDiff().
o Added indexByRow().


Version: 0.1.1 [2008-03-25]
o Added {col|row}OrderStats().
o Added {col|row}Ranges() and {col|row}{Min|Max}s().
o Added colMedians().
o Now anyMissing() support most data types as structures.


Version: 0.1.0 [2007-11-26]
o Imported the rowNnn() methods from Biobase.
o Created.
