Gives access to data visualisation methods that are relevant from the data scientist's point of view. The flagship idea of 'DataVisualizations' is the mirrored density plot (MD-plot) for either classified or non-classified multivariate data presented in Thrun et al. (2019)
Version 1.1.6 (CRAN, 2018-03-08) o Major Improvement: The MD-plot samples now data automatically above an threshold in order to be usuable for Big Data. o Bugfixes: In MD-plot the testing against uniform distribution now works also for one feauture. A crash is fixed where a columns has not even one finite value. o Bugfix: If colnames of Data are given in MD-plot but not unique, they are renamed to unique colnames. o Bugfix: Plot3D checks now that the length of Cls is equal to the number of rows of data. o Bugfix: ClassPDEplot did not plot all pdfs for SameKernelsAndRadius=0. o Improvement: ClassMDplot now jitters points instead of visualizing pdf if not enough data in class is given. o Bugfix: In Heatmap the x labels are now plotted correctly. o Bugfix: In ClassMDplot class names now work correctly. o Classplot and DualClassplot: Functions allow to plot one or two time series with a classification as scatter plots or line and scatter plots. Usefull to see if temporal clustering has time dependent variations and for Hidden Markov Models (see Mthrun/RHmm on GitHub).
Version 1.1.5 (CRAN, 2018-02-02) o Bugfix: The statistical testing in the MD-plot now is omitted if not enough unique values are given in some features. In such a case, only a scatter plot is plotted. o Naming Convention: Standardized plotting functions by removing "plot" in names except cases where it is conventional in other sources, e.g. MAplot. Older function names will be removed in the next CRAN version. o plotWorldmap renamed to Worldmap o plotChoroplethMap renamed to Choroplethmap o ClassBoxPlot renamed to ClassBoxplot o fanPlot renamed to Fanplot o pieChart renamed to Piechart o CrossTablePlot renamed to Crosstable o slopeChart renamed to Slopechart o plot3D renamed to Plot3D o InspectScatterOfData renamed to InspectScatterplots o PixelMatrixPlot renamed to Pixelmatrix o ShepardScatterPlot renamed to Sheparddiagram o ShepardDensityPlot renamed to ShepardPDEscatter o DualAxisLineChart renamed to DualaxisLinechart o SilhouettePlot renamed to Silhouetteplot o BoxplotData renamed to InspectBoxplots o QQplotWithFit renamed to QQplot o nanPlot is deprecated. The new function is PlotMissingvalues. o ClassViolinPlot is deprecated. The new function is ClassMDplot.
Version 1.1.4 (GitHub, 2018-11-17) o SignedLog: Allows to transform negativ values with logarithm. o Improvement: MD-plot allows for Scaling and Ordering of data and plots scattered points if a column has not enough values to perform density estimation. o Bugfix: stat_pde_density now works for only one value if other values are NaN.
Version 1.1.4 (CRAN, 2018-10-21) o DualAxisLineChart enables to visualize to lines in one plot overlaying them using ploty (e.g. two time series with two ranges of values) o Bugfix: PDEscatter now removes non-numeric values with na.rm=TRUE before xlim and ylim are defined o ProductRatioPlot: The plot is useful in the case where there are many instances of very small values, but a small number of very large ones o CrossTablePlot: Presents a heatmap with values and a cross table of given Data matrix of two features and a bin width or percentualized values o Update: plot3D function and documentation improved.
Version 1.1.3 (GitHub, 2018-07-07) o Improvement: MD-plot layout changes and plotting paramater added. o InspectCorrelation now visualizes the density and calcluates the spearman correlation index as a shortcut to PDEscatter. o Minor bugifx: MD-plot now uses ggExtra::rotateTextX() for better xaxis alignment of text.
Version 1.1.2 (GitHub, 2018-07-02) o Bugfix: InspectDistances methods argument now passed on to parallelDist::parDist.
Version 1.1.1 (CRAN 2018-06-30) o Improved visualization of MD-plot.
Version 1.1.0 (GitHub) o Vignette generated. o Bugfix: authors stated in Description regarding functions which were used in other dbt packages instead of this package.
Version 1.0.9 (GitHub) o ClassViolinPlot build on top of stat_pde_density for Data with Clustering. o Bugfix in stat_pde_density for special case of one value. o parallelDist integrated for faster distance computations.
Version 1.0.8 (GitHub) o Bugfix in stat_pde_density for special case of one value. o Minor bugfix in PDEscatter.
Version 1.0.7 (GitHub) o MD-plot: stat_pde_density added in order to integrate concept with ggplot2.
Version 1.0.1-1.0.6 (GitHub) o ClassBoxPlot function added for Data with Clustering. o ClassPDEplot function added for Data with Clustering. o ClassPDEplotMaxLikeli function added for Data with Clustering. o Minor bugfix in InspectVariable function. o Bugfix in internpiechart.
Version 1.0.0 (CRAN, 2018-05-06) o Complete package generated.
