2024-01-12 Valentin Todorov * * DESCRIPTION (Version): 0.5-0 * * R/cp_gen.R: added function for simulation of PARAFAC data sets 2023-03-16 Valentin Todorov * * DESCRIPTION (Version): 0.3-0 * * data/dorrit. rd: Added data set dorrit * R/cp_atld.R, cp_int2.R: added functions for CP with alternative * optimization techniques * R/Parafac.R: added option 'optim=c("als", "atld", "int2")' for using * alternative optimization techniques * tests/tparafac.Rout.save: Follow up to changes in robustbase 0.99-0 2022-10-15 Valentin Todorov * * DESCRIPTION (Version): 0.2-5 * * Fixed the references in the vignette * 2022-10-12 Valentin Todorov * * DESCRIPTION (Version): 0.2-4 * * Added vignette * 2022-02-08 Valentin Todorov * * DESCRIPTION (Version): 0.2-3 * * Fixed a problem with test results on some platforms * 2022-02-02 Valentin Todorov * * DESCRIPTION (Version): 0.2-2 * * * Added unit tests, improved Readme and improved documentation * Fixed a problem with test results on some platforms * 2022-01-24 Valentin Todorov * * DESCRIPTION (Version): 0.2-0 * * * Added Readme.md and development version published on GitHub * * R/Parafac.R, R/Tucker3.R: fixed a bug in the computation of the returned fit and fit percentage values. * * R/Tucker3.R: initialization option implemented (start=) * * R/Parafac.R, R/Tucker3.R, R/plot-utils.R: added clr transformation - parameter ilr=TRUE/FALSE * in Parafac() and Tucker3() changed to coda.transform=c("none", "ilr", "clr") * * R/Parafac.R, function .cutoff.sd() fixed a bug, now Parafac works for ncomp=1 and robust=TRUE. * actually the issue was in rrcov/PcaHubert and was fixed also there. * * man/plot-methods.Rd - fixed the description also for the plot for Parafac objects * * DESCRIPTION, NAMESPACE and others: All functions which were adapted from ThreeWay are now removed and * imported from ThreeWay (added to DESCRIPTION and NAMESPACE) * * DESCRIPTION, NAMESPACE and others: All functions which were adapted from pracma are now removed and * imported from pracma (added to DESCRIPTION and NAMESPACE) * * DESCRIPTION, NAMESPACE and others: dependence on rrcov removed, all necessary functions are imported * * R\Parafac.R, Tucker3.R: if robust=TRUE and center=TRUE and/or scale=TRUE, robust centering and scaling * through median and mad is performed. Of course the user can select any robust centering/scaling * function from the available in robustbase (or elsewhere). * * R\Parafac.R, Tucker3.R - the parameter crit was not used always - fixed * 2020-01-14 Valentin Todorov * * DESCRIPTION (Version): 0.1-18 * DESCRIPTION (Version): 0.1-17 * Removed dependency to ThreeWay * NAMESPACE fixed to export correctly only the user-level functions * data/amino.rda, man/amino.rda - added data set amino * Parameter ilr=TRUE/FALSE in Parafac () and Tucker3() changed to coda.transform=c("none", "ilr") * Added utility and matrix utility functions: mtrace, krp, orth, orthmax2, congruence, varimcoco * 2017-08-01 Valentin Todorov * * DESCRIPTION (Version): 0.1-12 * R/utils.R - added function do3Rotate.tucker3() to rotate a Tucker3 solution; * - calls .varimcoco(), adapted from ThreeWay; * - in turn it calls orth() and orthmax2() * R/utils - do3Scale() updated to perform double centering. Also, Tucker3 and Parafac updated to * use double centering * R/utils - added function ilrArray() to perform ilr transformation on an array * * 2017-06-19 Valentin Todorov * * DESCRIPTION (Version): 0.1-8, 0.1-9, 0.1-10 * * First version submitted to CRAN * 2014-12-04 Valentin Todorov * * DESCRIPTION (Version): 0.1-4 * * Added data set waterquality * * 2014-12-03 Valentin Todorov * * DESCRIPTION (Version): 0.1-3 * * Added data set Arno * * 2014-11-20 Valentin Todorov * * DESCRIPTION (Version): 0.1-2 * * Added PARAFAC model * * 2014-07-10 Valentin Todorov * 0.1-1 * Created *
