• It is now possible to set the loss function to be used when trying to
  optimize the Euler diagram layout via loss and loss_aggregator.
  There is a new vignette that showcases this new feature.

Minor Changes

  deprecated and removed to fix sanitizer warnings.

Full Changelog: v6.1.1...v7.0.0

eulerr 6.1.1

Minor changes

• citation to conference paper added to inst/CITATION
• error messages for erroneous input have been improved in several places
• switched PI to M_PI to support STRICT_R_HEADERS in C++ code
  (#82, thanks @eddelbuettel)

Bug fixes

• error in documentation for list method has been fixed, thanks @gprezza (#77)

eulerr 6.1.0

Minor changes

• Label repelling (activated by calling euler() with adjust_labels = TRUE)
  no longer repels text labels away from the edges of the shapes in
  the diagram.

Bug fixes

• Rectify sanitizer error from clang-ASAN test environment.

eulerr 6.0.2

Bug fixes

• Set stringsAsFactors = TRUE inside all relevant functions in euler()
  to avoid errors in upcoming R version.
• Fix broken link in euler under the hood vignette.

eulerr 6.0.0

New features

• In plot.euler(), percentages can be added to the plot in addition to or
  instead of counts by providing a list to the quantities argument
  with an item type that can take any combination of counts and percent.
  This change also comes with a redesign of the grid graphics
  implementation for labels.
• eulerr_options() gains a new argument
  padding which controls the amount of padding between labels and quantities.
  (#48)
• plot.euler() now uses code from the ggrepel package to prevent
  labels from overlapping or escaping the plot area if adjust_labels is
  set to TRUE.
• A new vignette featuring a gallery of plots from the package has been
  added.

Minor changes

• The default cex for quantity labels has changed from 1.0 to 0.9.
• Labels for sets that overlap are now merged (partly fixes #45)
• The fill colors for sets which are completely contained within another set
  are now once again composed of a mix of the color of the subset and
  the superset.
• Plotting data has been exposed in a data slot in the object created
  by calling to plot.euler() (#57)

Bug fixes

• An error in layout normalization that occurred sometimes
  with ellipses has been fixed.

eulerr 5.1.0

eulerr 5.1.0

New features

• venn() is a new function that produces Venn diagrams for up to
  5 sets. The interface
  is almost identical to euler() except that a single integer
  can also be provided. A new vignette, Venn diagrams with eulerr,
  examplifies its use.

Minor changes

• Calculations for the strips in plot.euler() when a list of
  Euler diagrams is given has been improved. Setting fontsize or
  cex now results in appropriately sized strips as one would expect.
• Tiny overlaps (where the fraction of the area is less than one
  thousandth of the largest overlap) in the final diagram are no longer
  plotted.
• eulergram() objects from plot.euler() now have a proper grob name
  for the canvas grob, so that extracting information from them is easier.

Bug fixes

• Return value documentation for euler() now correctly says "ellipses"
  and not "coefficients".
• data.frame or matrix inputs now work properly
  when values are given as numerics. (#42)
• Fixed some spelling errors in news and vignettes.

eulerr 5.0.0

New features

• error_plot() is a new function that offers diagnostic plots of
  fits from euler(), letting the user visualize the error in the
  resulting Euler diagram.

Major changes

• euler() once again uses the residual sums of squares, rather than the
  stress metric, as optimization objective, which means that
  output is always scaled appropriately to input (#28).
• plot.euler() now uses the
  polylabelr package to position
  labels for the overlaps of the ellipses, which has improved
  performance in plotting complicated diagrams considerably and reduced
  the amount of code in this package greatly.
• The c++ internals have been rewritten using more memory-efficient, performant
  and expressive code.

Minor changes

• The euler.data.frame() method (and by proxy the euler.matrix() method)
  can now take matrices with factors in addition to the previously supported
  logical and integer (binary) input. The function will dummy code the variables
  for the user.
• A few performance fixes.
• Additional unit tests.
• Previously deprecated arguments to plot.euler() have been made defunct.
• Added a data set, plants, to exemplify the list method for euler().
• Added a data set, fruits, to exemplify the data.frame method for euler().
• euler.data.frame() gains an argument sep, which is a character vector
  used to separate dummy-coded factors if there are factors or characters in the
  input.
• Added a data set, organisms, to exemplify the matrix method for euler().
• Added a data set, pain, to exemplify the table method for euler().
• euler.table() gains an argument, factor_names, for specifying
  whether the factor names should be included when generating dummy-coded
  variables in case the input is a data.frame with character or factor vectors
  or if the input is a table with more than two columns or rows.
• Parts of the eulerr under the hood vignette has been branched off into
  a new vignette regarding visualization.

Bug fixes

• Empty combinations can now be provided and will be plotted (generating
  completely blank plots).
• euler.list() now passes its ellipsis argument along properly. (#33,
  thanks, @banfai)
• Several spelling and grammar mistakes were corrected in vignettes and
  documentation.

eulerr 4.1.0

Minor changes

• plot.euler() now returns a gTree object. All of the plotting mechanisms
  are now also found in this function and plot.eulergram() and
  print.eulergram() basically just call grid::grid.draw() on the result
  of plot.euler(). This change means that functions such as
  gridExtra::grid.arrange() now work as one would intuit on the objects
  produced by plot.euler().
• Fitting and plotting euler diagrams with empty sets is now allowed (#23).
  Empty sets in the input will be returned as NA in the resulting
  data.frame of ellipses.
• The last-ditch optimizer has been switched back to GenSA::GenSA() from
  RcppDE::DEoptim().

Bug fixes

• The grid parameters available for edges are now correctly specified in
  the manual for plot.euler().
• euler.data.frame() now works as expected for tibbles (from the tibble
  package) when argument by is used.
