=== randtoolbox: an R package for random number generation and testing === Version 1.30.0 ============= - disable the use of set.generator(name="congruRand",...) - clean up C code Version 1.20 (never released on CRAN) ============= - translate Fortran code of Diethelm Wuertz for Halton sequence into C. - by default halton() use the C code slightly faster than the Fortran code. - start to translate Fortran code of Diethelm Wuertz for Sobol sequence into C. - add defensive programming for QMC. BUGS FIX - scrambling = 1, 3 for Sobol sequences (provided by Makoto Matsumoto and Mutsuo Saito). - mixed = TRUE for QMC sequences. - correct use of 64-bit integer type - correct failures in if statements (length > 1 in coercion to logical) in quasiRNG.R and pseudoRNG.R NOTE FIX - usage of R_useDynamicSymbols to preclude compilation NOTEs, better registration of native routines and reduced symbol visibility. Version 1.17 and 1.17.1 ============= - change DESCRIPTION file. - update NAMESPACE for R 3.3.0. - update the LICENSE file. - raise a warning when scrambling for Sobol sequences is incorrect. BUG REPORT (by Dan Souther, Kemal Dincer Dingec, Marius Hofert, Nicolas Chopin, Andrei Kostyrka) - scrambling = 1, 3 for Sobol sequences. (by Hiroyuki Kawakatsu) - mixed = TRUE for QMC sequences. Version 1.16 ============= - change title and other minor things in vignettes. Version 1.15 ============= - remove the use of 'long long' in some C code. - update LICENCE file. - move autoconf files to tools directory. - no longer use a4 paper format in vignette. Version 1.14 ============= - change licence from BSD_2_clause to BSD_3_clause. - minor change. Version 1.13 ============= - this version is one of the last versions working with package rngWELL >= 0.11-0. - change licence from BSD to BSD_2_clause. NOTE FIX - remove NOTES appearing in R CMD check. Version 1.12 ============= NEW FEATURES - add new test files. - increase the possible dimension of Halton sequences. WARNING FIX in Fortran files - remove an array over-run (reported by Brian Ripley) and tab characters in LowDiscrepancy.f. Version 1.11 ============= - this version is one of the last versions working with package rngWELL == 0.10-x. NOTES FIXES - this version use packageStartupMessage function for the .onAttach rather than the cat function. - remove a printf in KnuthTAOCP2002.c WARNING FIXES in C files - remove warnings with Wall and pedantic gcc options. For this purpose, files randtoolbox/src/Makevars and rngWELL/src/Makevars now contain a line, uncommenting which includes Wall and pedantic. See https://stat.ethz.ch/pipermail/r-sig-mac/2008-August/005251.html BUG FIX - the package crashes when the dimension was 0 in RNG functions, reported by David LeBauer. Version 1.10 ============= NEW FEATURES - update the man page pseudoRNG.Rd and quasiRNG.Rd with MT19937 and other minor improvements. - on loading, the package print the overview man page. WARNING FIXES - fix some warnings following the release of R 2.13.0: the Makefile and the man page of runifInterface. - fix a warning in the MT19937 file. BUG FIX - remove implicit type declaration in the LowDiscrepancy fortran file, which causes errors with GCC 4.6 compilers. Version 1.09 ============= NEW FEATURES - start runif interface for congruential generator and WELL RNG, - vignette contains two chapters, - start to test true randomness (not included in this version), - increase the speed and accuracy of Halton and Sobol sequences. STRUCTURAL CHANGE - Before version 1.09, there was a lot of different (and incompatible) licences in this package, namely, GPL, BSD, public domain, etc... (cf. 1.08-version DESCRIPTION file of this package). - From 1.09, all this code of this package is under the new BSD licence. A copy of the BSD licence is available at http://www.opensource.org/licenses/bsd-license.php - extract Pierre L'Ecuyer's code from randtoolbox and put it in a dedicated package rngWELL, - depends now on rngWELL. AUTHORS - all the code of this package except the ones listed below was written by Yohan Chalabi, Christophe Dutang, Petr Savicky and Diethelm Wuertz. - the code for SF-Mersenne Twister belongs to M. Matsumoto and M. Saito, which is under the new BSD licence. - the code for Knuth-TAOCP-2002 generator belongs to D. E. Knuth. This code is in the public domain and freely copyable. BUG FIX - normal transformation of Halton and Sobol sequences is correct. BUG REPORT - Halton and Sobol sequences did not work on 64bit architecture when using normal transformation reported by Anirban Mukherjee, - Sobol sequences for dimension > 2 need to be tested. Version 1.08 (never released on CRAN) ============= NEW FEATURES - add function get.primes, - table of primes moved from randtoolbox.c to primes.h and compressed by storing half difference from the previous prime instead of each prime (except for 2 and 3), - start runifinterface. Version 1.07 ============= NEW FEATURES - integrate code for Halton, Sobol sequence from fBasics (Rmetrics), - randoolbox is now part of Rmetrics project (available on R-forge), - increase the speed of congruRand. BUG FIXES - fix setSeed function, - a warning shows up on 64 bit architecture. BUG REPORT - setting the seed with WELL's RNGs was not correct, reported by Petr Savicky. Version 1.06 ============= BUG FIX - the degree of freedom is now correct for the order test. BUG REPORT - Astley Lin reports that the degree-of-freedom(df) of chi-square test is wrong for the order test. Version 1.05 ============= NEW FEATURES - add new WELL generators based on L'Ecuyer's code, - add the Sobol and Halton sequences from fOptions package. BUG FIX - Yes, it compiles on 64bit linux both on CRAN and R-forge. Version 1.04 ============= BUG REPORT - the package does not compil on Fedora 8 x86_64 boxes, reported by Brian Ripley. Version 1.03 ============= NEW FEATURES - add the WELL generator thanks to the code of P. L'Ecuyer, - SFMT now allows for different mersenne exponents as well as parameter sets, - increase the possible dimension for Torus algorithm from 1000 to 100 000, - add the RAN_ARRAY generator of Knuth TAOCP (2002), - the function setRandSeed has be renamed by setSeed, - update the vignette. Version 1.02 ============= NEW FEATURES - more random generation tests such as collision test and order test, - poker test is generalized to any dimension, - some auxiliary functions, - a detailed vignette on generating and testing random generation. BUG FIXES - on windows, when the seed was not fixed by the user, we use the machine time. But we use only seconds of machine time not micro second like on unix-like system. Hence a call like this > for(i in 1:10) print(congruRand(1)) produces the same output. Now it is fixed. Version 1.01 (never released on CRAN) ============= NEW FEATURES - add withtorus option for SFMT function, - improve output of tests. Version 1.00 ============= - Initial release based on the torus package (which is no longer available).
