• Updated type checking to accomodate new 'matrix' inheritance.

bigmemory 2017-11-19

• Re-added functions to assign based on column and row names.

bigmemory 2017-11-08

• Memory leak problem solved.

bigmemory 2016-09-21

• Fixed a bug with handling raw bytes. Now it is possible to use big.matrix to store arbitrary R object (using serialization). If you want to make sure that bigmemory big.matrix handles raw data, add "bigmemory (>=4.5.21)" to the Depends stanza in the Description.

• Enabled use of Rcpp package to simply code and create smaller barrier to adding additional extensions.
• Added new method to big.matrix objects, allocation_size, to easily check the size of the object in memory.
• Float type matrices have now been added to enable single precision analytics.

bigmemory 2013-03-09

• We missed a NEWS entry. Windows support is temporarily suspended due to issues with the Boost headers.
• We now depend on bigmemory.sri (a trivial dependency relating to our big.matrix descriptors) and new package BH (for Boost headers).

bigmemory 2011-06-29

• Modified deepcopy() with C code (thanks to Zarrar for this)
• Added -fpermissive to possibly address a compilation issue in Linux
• Added -lm to address a linking problem with math.h
• Fixed a problem with reading all 0's in a column in read.big.matrix()
• We note that there may be an inconsistency with read.big.matrix() and write.big.matrix() that needs to be addressed.

bigmemory 2010-10-30

• Modified configure to handle a Solaris problem.
• Added definition of __C99FEATURES__ to isna.hpp; hopefully won't break anything.

bigmemory 2010-05-16

• Set proper default value op='AND' for mwhich()

bigmemory 2010-05-08

• The configuration process has been streamlined to avoid warnings and allow for support of Sun Studio compiler on Linux.

bigmemory 2010-05-06

• bigmemory >= 2.2.0 is accompanied by sister packages biganalytics and bigtabulate; mutexes (locking) are abstracted to package synchronicity, available now on R-Forge and soon to be uploaded to CRAN. Package bigalgebra is on R-Forge as a beta version while we sort through the range of library configuration options.
