arulesViz_1.5-1

arulesViz 1.5-1 (11/18/2021)

New features

• plot method "grouped matrix" gained parameter grouped to pass on a grouped matrix.
• associations2igraph gained parameter associationsAsNodes.
• plot method graph with engine vizNetwork can now display itemsets.
• plot gained parameter limit to print only the top limit rules.
• plot method graph with ggraph (ggplot2) gained parameters asEdges = TRUE to represent associations as edges instead of nodes.

Changes

• we use now a better check for installed suggested packages.
• method graph uses now ggraph.

Bugfixes

• plot method graph with engine htmlwidget shows now labels correctly.

arulesViz_1.5.0

New features

• ggplot2 is now the default engine for most plots.
• grouped matrix visualization has now engine ggplot and htmlwidget.
• conversion from associations to igraph is now exposed.
• conversion from rules to matrix and groupedMatrix are now exposed.
• "help" can now be specified for plot for method, engine, and control.
• ruleExplorer lost parameter and gained sidebarWidth and chartHeight.

Bug Fixes

• Fixed rounding bug in inspectDT.
• Fixed jitter for scatter plot using engine plotly.
• Fixed reordering for grouped matrix (engine plotly).

arulesViz_1.4-0

New features

• plot methods "scatterplots" and "matrix" have now engine ggplot2.

Removed functions

• cleaned namespace. E.g., grid is now an import (instead of a dependency).
• plotly_arules was removed from the interface. Use plot with engine "plotly" or "htmlwidget."
• experimental support for iplots was removed.

Bug Fixes

• fixed bug that prevented shading = NA in plotting method graph.
• fixed some control parameter handling and added more examples for plot method graph.
• fixed additional item shown in LHS for grouped matrix plot (reported by Tasos Fasoulis).

arulesViz_1.3-3

New features

• ruleExplorer got a cleaner interface and several new features.

Bug Fix

• plot with method "paracoord" works now also with a single item in the LHS.

arulesViz_1.3-2

Bug Fix

• ruleExplorer now checks for an excessive number of items so shiny does not freeze.
• plot with method matrix: control option reorder = "similarity" works now again.

arulesViz_1.3-1

New features

• ruleExplorer: interactive visualization with shiny was added.
• plot method matrix now supports different reordering methods: 'none',
  'measure', 'support/confidence', 'similarity'. The default is measure,
  the measure used for shading.
• measure and shading now auto-completes measure names.

Changes

• plotly_arules is deprecated use plot with engine = "plotly" instead

Bug Fix

• Fixed problem with quality measures (offset of 1) when creating igraph
  graphs (reported by sostahl).

arulesViz_1.2.1

New features

• plot method "grouped" now shows the most interesting items instead of the most frequent items to represent antecedents. Also, if more than 10 RHS items are found, then only the 10 most important are shown (see control argument rhs_max).
• arules_plotly uses now signif instead of round for quality measures.
• arules_plotly implements now jitter to reduce overplotting (defaults to .1 if overplotting would occur).
• arules_plotly shows correct rule indices for too large rule sets.
• scatterplot also defaults jitter to .2 if overplotting would occur.
• scatterplot now handles Inf with a warning.

arulesViz_1.2-0

Changes in version 1.2-0 (10/02/2016)

• improved graphical parameters for the grouped matrix plot.
• default color scheme is now a grey-red ramp.
• added inspectDT for interactive rules inspection using package DT.
• added plotyl_arules, interactive plots with plotly.

arulesViz_1.1-1

Changes in version 1.1-1 (04/10/2016

• plot method ordered now passes control arguments on correctly.

arulesViz_1.1-0

• abbreviate has been moved to arules.
• fixed bug in grouped plots when the quality of many rules is identical.
• plots use now heat colors.
• scatterplots use now for lift zlim starting at 1.
