# # NEWS for R package bigmemory # # See also the Bigmemory Project: # http://www.bigmemory.org # Jay and Mike # # Jay Emerson # Mike Kane # Charles Determan 2019-12-20 Michael Kane * Updated type checking to accomodate new `matrix` inheritance. 2017-11-19 Michael Kane * Re-added functions to assign based on column and row names. 2017-11-08 Michael Kane * Memory leak problem solved. 2016-09-21 Adam Ryczkowski * 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. 2014-04-15 Mike and Charles * 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. 2013-03-09 Jay and Mike * 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). 2011-06-29 Jay and Mike * 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. 2010-10-30 Jay * Modified configure to handle a Solaris problem. * Added definition of __C99FEATURES__ to isna.hpp; hopefully won't break anything. 2010-05-16 Jay * Set proper default value op='AND' for mwhich() 2010-05-08 Jay * The configuration process has been streamlined to avoid warnings and allow for support of Sun Studio compiler on Linux. 2010-05-06 Jay and Mike * 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.
