clusterGeneration v1.3.8 (creation date: 2023-08-15) ================= Changes: * (1) fixed a bug in genMeanCov(): commented out for loop about 'eg' * (2) fixed a bug in findNeighbors(): 'pos <- which(tmp < -1 || tmp > 1)' * should be 'pos <- which(tmp < -1 | tmp > 1)' * (3) fixed format in NEWS file * (4) fixed the bug 'Escaped LaTeX specials: \_' in Rd files clusterGeneration v1.3.7 (creation date: 2020-12-12) ================= Changes: * (1) added function "genOrthogonal" to export list clusterGeneration v1.3.6 (creation date: 2020-11-21) ================= Changes: * (1) added "na.rm=TRUE" when calling 'sum', 'max' * (2) when call a function, explicitly call its input * (3) fixed a bub in function 'genMeanCov': when calling 'genPositiveDefMat', the input 'eigenvalue' was missing. * (4) added input argument 'eigenvalue' to function 'genMeanCov' and 'genRandomClust' and 'genNoisyMeanCov' and 'simClustDesign' clusterGeneration v1.3.5 (creation date: 2020-10-03) ================= Changes: * (1) add new argument "eigenvalue" so that user can supply own eigenvalues for algorithm covMethod=c("eigen") * (2) in genPositiveDefMat, using crossprod(Q * sqrt(egvalues)) instead of Sigma <- Q %*% u %*% t(Q) leads to nice improvements (3-4 times faster) when simulating large matrices (dim>500). Reason is that the new code does not require to form the u matrix, and that crossprod() is quite faster when used with a single argument (exploiting that output will be symmetric) * Thanks Dr. Matthieu Stigler (matthieu.stigler@gmail.com) for these 2 suggestions! * (3) change maintainer's email address to clusterGeneration v1.3.2 (creation date: 2015-02-14) ================= Changes: * (1) fixed a few bugs in function 'getSepProjData': * 'u.cl <- unique(cl)' should be * 'u.cl <- sort(unique(cl)' * 'yi <- y[cl == u.cl[i], , drop = FALSE]' * should be * 'yi <- y[which(cl == u.cl[i]), , drop = FALSE]' clusterGeneration v1.3.1 (creation date: 2013-01-07) ================= Changes: * (1) added a space between 'Weiliang Qiu' and * '' in the 'Maintainer' slot * in the DESCRIPTION file * Thank Dr. Kurt Hornik for his kind help! clusterGeneration v1.3.0 (creation date: 2013-01-06) ================= Changes: * (1) rename 'log.txt' file to 'NEWS'. * Thanks for Mr. Suraj Gupta () for this suggestion! clusterGeneration v1.2.9 (creation date: 2012-04-02) ================= Changes: * (1) fixed a bug pointed by Dr. Anton Korobeynikov * * Dear Dr. Weiliang Qiu, * * Recently we tried to used your package clusterGeneration but found * that the behavior of genRandomClust() with clustszind == 3 is * definitely wrong compared to the one documented. * After looking into the implementation it became obvious that * genMemSize() function does wrong things: it tries to sample from 1:G * using provided clusterSizes as weights. Surely the output clusters * have wrong sizes (not the ones specified). * * The fix is pretty simple: change the code for clustszind == 3 to * something like this: * * mem <- sample(unlist(lapply(1:G, function(x) rep.int(x, times = * clustSizes[x])))) * N <- sum(clustSizes) * * Or, maybe if you want to keep the current behavior it'd be better to * introduce new clustszind variant. * * * (2) add 'clustSizes<-as.integer(clustSizes)' before checking * '!is.integer(clustSizes[i])' clusterGeneration v1.2.8 (creation date: 2012-03-19) ================= Changes: * (1) fixed a few warning messages: * (a)>> * checking R code for possible problems ... NOTE *genNoisyMeanCov: warning in eigen(Sigma.noisy, sym = TRUE): partial * argument match of 'sym' to 'symmetric' * (b)>>> ** running examples for arch 'i386' ...
