Changes for R-package Luminescence

Version 0.9.4 - parameter name lw changed to l in all functions - Function GUI() extended - Function get.l.opt() added - Function get.l() added - Function get.limits() added - Function get.q() added - Function model.em() added - Evaluation outpout of EMMA() extended - Axes labels of EMMA() changed - function create.sample() removed - example data set changed

Version 0.9.3 - Function GUI() added - Standard EMMA() output significantly extended - Multicore option added to test.parameters() - Output of test.robustness() extended by mEt, mEm, mEn, mRm, mRn - All code/documentation changed to Roxygen - Some rephrasing of function documentations - Code optimisation (parallelisation instead of loops) - EM ID assignment bug fixed - Bug removed (twisted plots of clos vs. rows) - Bug in X_m calculation fixed, now matrix is rescaled - Bug in EMMA() removed (wrongly set bracket in Vqs calculation) - Minor bug fixes

Version 0.9.2 - Function create.sample() was added - Example data was enlarged to facilitate function examples - Function lw.max() was added

Version 0.9.1 (2013-09-13) - Function mix.EM(): as.numeric() added to proportion parameter, to also support matrices as input - Function EMMA(), test.lw(), test.L(): weight quantile calulation implemented as sapply() rather than separate function definition - Function EMMA(), test.lw(), test.L(): parameters ls, Vqr, Vqn, Vqsn corrected for geometry (now: ls[2,m], Vq...[q,m]) - Function EMMA(): two redundant but convenient function values added: $loadings and $scores - Function test.parameters(): y-axes limits set automatically to prevent false display of data - Function test.lw(): test for valid EMMA()$Mqs matrix added - Function check.data(): lw-validity-test now supports scalars for lw - Function define.limits() was added

Version 0.9.0 (2013-06-21) - Initial version
