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

Version: 0.8.14 [2013-11-23]
o MEMORY: Updated all functions to do a better job of cleaning out
  temporarily allocated objects as soon as possible such that the
  garbage collector can remove them sooner, iff wanted.  This 
  increase the chance for a smaller memory footprint.


Version: 0.8.13 [2013-10-08]
o Added argument 'right' to binCounts() and binMeans() to specify
  whether binning should be done by (u,v] or [u,v).  Added system
  tests validating the correctness of the two cases.
o Bumped up package dependencies.


Version: 0.8.12 [2013-09-26]
o SPEEDUP: Now utilizing anyMissing() everywhere possible.


Version: 0.8.11 [2013-09-21]
o ROBUSTNESS: Now importing 'loadMethod' from 'methods' package such
  that 'matrixStats' S4-based methods also work when 'methods' is
  not loaded, e.g. when 'Rscript' is used, cf. Section 'Default
  packages' in 'R Installation and Administration'.
o ROBUSTNESS: Updates package system tests such that the can run
  with only the 'base' package loaded.


Version: 0.8.10 [2013-09-15]
o CLEANUP: Now only importing two functions from the 'methods' package.
o Bumped up package dependencies.


Version: 0.8.9 [2013-08-29]
o CLEANUP: Now the package startup message acknowledges argument
  'quietly' of library()/require().


Version: 0.8.8 [2013-07-29]
o DOCUMENTATION: The dimension of the return value was swapped
  in help("rowQuantiles").


Version: 0.8.7 [2013-07-28]
o SPEEDUP: Made (col|row)Mins() and (col|row)Maxs() much faster.
o BUG FIX: rowRanges(x) on an Nx0 matrix would give an error.
  Same for colRanges(x) on an 0xN matrix.  Added system tests
  for these and other special cases.


Version: 0.8.6 [2013-07-20]
o Forgot to declare S3 methods (col|row)WeightedMedians().
o Bumped up package dependencies.


Version: 0.8.5 [2013-05-25]
o Minor speedup of (col|row)Tabulates() by replacing rm() calls
  with NULL assignments.


Version: 0.8.4 [2013-05-20]
o CRAN POLICY: Now all Rd \usage{} lines are at most 90 characters long.


Version: 0.8.3 [2013-05-10]
o SPEEDUP: binCounts() and binMeans() now uses Hoare's Quicksort
  for presorting 'x' before counting/averaging.  They also no longer
  test in every iteration (=for every data point) whether the last
  bin has been reached or not, but only after completing a bin.


Version: 0.8.2 [2013-05-02]
o DOCUMENTATION: Minor corrections and updates to help pages.


Version: 0.8.1 [2013-05-02]
o BUG FIX: Native code of logSumExp() used an invalid check for
  missing value of an integer argument.  Detected by Brian Ripley
  upon CRAN submission.


Version: 0.8.0 [2013-05-01]
o Added logSumExp(lx) and (col|row)LogSumExps(lx) for accurately
  computing of log(sum(exp(lx))) for standalone vectors, and
  row and column vectors of matrices. Thanks to Nakayama (Japan)
  for the suggestion and contributing a draft in R.


Version: 0.7.1 [2013-04-23]
o Added argument 'preserveShape' to colRanks().  For backward
  compatibility the default is preserveShape=FALSE, but it may
  change in the future.
o BUG FIX: Since v0.6.4, (col|row)Ranks() gave the incorrect
  results for integer matrices with missing values.
o BUG FIX: Since v0.6.4, (col|row)Medians() for integers would
  calculate ties as floor(tieAvg).


Version: 0.7.0 [2013-01-14]
o Now (col|row)Ranks() support "max" (default), "min" and
  "average" for argument 'ties.method'.  Added system tests
  validation these cases.  Thanks Peter Langfelder (UCLA) for
  contributing this.


Version: 0.6.4 [2013-01-13]
o Added argument 'ties.method' to rowRanks() and colRanks(), but
  still only support for "max" (as before).
o ROBUSTNESS: Lots of cleanup of the internal/native code.  Native
  code for integer and double cases have been harmonized and are
  now generated from a common code template.  This was inspired by
  code contributions from Peter Langfelder (UCLA).


Version: 0.6.3 [2013-01-13]
o Added anyMissing() for data type 'raw', which always returns FALSE.
o ROBUSTNESS: Added system test for anyMissing().
o ROBUSTNESS: Now S3 methods are declared in the namespace.


Version: 0.6.2 [2012-11-15]
o CRAN POLICY: Made example(weightedMedian) faster.


Version: 0.6.1 [2012-10-10]
o BUG FIX: In some cases binCounts() and binMeans() could try to go
  past the last bin resulting a core dump.
o BUG FIX: binCounts() and binMeans() would return random/garbage
  values for bins that were beyond the last data point.


Version: 0.6.0 [2012-10-04]
o Added binMeans() for fast sample-mean calculation in bins.
  Thanks to Martin Morgan at the Fred Hutchinson Cancer Research
  Center, Seattle, for contributing the core code for this.
o Added binCounts() for fast element counting in bins.


Version: 0.5.3 [2012-09-10]
o CRAN POLICY: Replaced the .Internal(psort(...)) call with
  a call to a new internal partial sorting function, which
  utilizes the native rPsort() part of the R internals.


Version: 0.5.2 [2012-07-02]
o Updated package dependencies to match CRAN.


Version: 0.5.1 [2012-06-25]
o GENERALIZATION: Now (col|row)Prods() handle missing values.
o BUG FIX: In certain cases, (col|row)Prods() would return NA instead
  of 0 for some elements.  Added a redundancy test for the case.
  Thanks Brenton Kenkel at University of Rochester for reporting on this.
o Now this package only imports methods.


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 depends 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 (col|row)Medians(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 (col|row)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 gave 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.
