diceR - diceR 3.0.0

• There were errors running tests on clang-UBSAN and gcc-UBSAN builds, due to usage of functions from clusterSim. Reinstate internal and external functions from clusterCrit package, which is no longer archived.
• Use new parameter verbose in dice() to control console printouts of main tasks being performed instead of using progress
• Refactor graph_heatmap() to use pheatmap::pheatmap() since NMF::aheatmap() throws a gridPLT() error whenever it is run in a script or interactively, but not in R markdown documents. Thus there are run time errors when used in unit tests and examples. See renozao/NMF#65
• Remove deprecated function usage

diceR - diceR 2.0.0

Internal and external validity indices were refactored to avoid using helper functions from the clusterCrit package, which is scheduled to be archived. Please adapt your code if it extracts deprecated validity indices, as described below.

• Calinski-Harabasz index now calculated using clusterSim::index.G1()
• Dunn index now calculated using clValid::dunn()
• Gamma index now calculated using clusterSim::index.G2()
• C-index now calculated using clusterSim::index.C()
• Davies-Bouldin now calculated using clusterSim::index.DB()
• SD index now calculated correctly using clv::clv.SD() and helper functions from clv. Previously only the total separation between clusters was returned.
• S_Dbw index now calculated using clv::clv.SDbw() and helper functions from clv
• Rousseeuw's Silhouette now calculated using clusterSim::index.S()
• PBM, Tau, McClain-Rao, Ray-Turi, and G-plus indices were removed as equivalent implementations from other packages were not found. They may be reinstated in the future.
• All external validity indices are now calculated manually using counts from the concordance matrix (Hubert, Jaccard, McNemar, and Rand indices)
• Best index value (maximum or minimum) now calculated manually

Decreased dependencies

The following steps were taken to minimize dependencies and ensure that diceR can still run on R 3.5:

• Removed cli and RColorBrewer from Imports

• Moved apcluster, blockcluster, cluster, dbscan, e1071, kernlab, and kohonen to Suggests, use their specific clustering algorithms conditionally. mclust needs to be in Imports because mclust::mclustBIC() needs to be imported

• Moved sigclust to Suggests, use within sigclust() conditionally

• Moved progress to Suggests, use within consensus_cluster() conditionally

• Moved poLCA to Suggests, use within dice() conditionally

• Moved Rtsne to Suggests, use within prepare_data() conditionally

• Removed old dependency grDevices from Imports

• Set minimum version to R (>= 3.5) for klaR dependency questionr

• In ev_confmat(), use yardstick::conf_mat() instead of caret::confusionMatrix(). caret has many dependencies, so best to avoid using it

• In graph_heatmap(), use NMF::aheatmap() instead of gplots::heatmap.2(). gplots depends on caTools, which now relies on R (>= 3.6)

• In consensus_cluster(), use stringr::str_to_title() instead of Hmisc::capitalize(). Hmisc depends on latticeExtra, which now relies on R (>= 3.6)

• In graph_delta_area(), use base solution instead of flux::auc(). flux also depends on caTools

• In prepare_data(), use own implementation of quantable::robustscale() with all of the former function's defaults. quantable also depends on caTools

• Specify Bioconductor installation on Travis and AppVeyor since NMF now Imports Biobase

Minor improvements and bug fixes

• Remove suppressWarnings(RNGversion("3.5.0")) after updating R version

• Run LCA() unit test on imputed clustering object

• Remove internal validity measures with any Inf entries for consensus_reweigh()

• Use a cleaner, more robust method of removing Rplots.pdf after running test-graphs.R

• Ensure column binding with purrr::map_dfc() in consensus_rank()

• Replaced dplyr::bind_cols() with purrr::flatten_dfc() to suppress warning "Outer names are only allowed for unnamed scalar" in get_cdf()

• update roxygen and docs
