ggforce (development version)

• Cnages to comply with latest ggplot2 release

ggforce 0.3.1

• Better fix for gganimate compatibility (#157)

ggforce 0.3.0

• Added facet_matrix() in order to facet different data columns into different rows and columns in a grid, in order to make e.g. scatterplot matrices and pairs plot
• Added geom_autopoint() and position_auto() to jitter points based on the type of positional scales in the panel
• Added geom_autohistogram() and geom_autodensity() for facilitating distribution plots along the diagonal in a facet_matrix() plot.
• Added facet_row() and facet_col to have one-dimensional facet_wrap() with possibility of variable sizing.
• Stats should now always keep the old group variable (potentially with something added), making them work with gganimate
• Removed the Visual Guide vignette to reduce compilation time. See the website for an overview of all functionality with compiled examples (https://ggforce.data-imaginist.com)

ggforce 0.2.2

• Fixed a regression in geom_sina() where the computation would fail with a warning due to tolower() being masked (#134, #135).

ggforce 0.2.1

• Fixed a bug in the calculation of open and closed b-splines, where the interval would exceed the defined region and result in an out-of-bounds memory error

ggforce 0.2.0

New features

• linear_trans for composing linear transformation using rotate, stretch, shear, reflect, and translate
• facet_stereo added for creating stereographic projections
• geom_voronoi_[tile|segment], geom_delaunay_[tile|segment|segment2], and stat_delvor_summary has been added for tesselation and triangulation.
• geom_spiro has been added for drawing spirographs
• Add geom_ellipse for drawing regular and superellipses
• Add geom_regon for drawing regular polygons
• Add geom_diagonal, geom_diagonal_wide and geom_parallel_sets for drawing parallel sets diagrams and other visualizations based on diagonals.
• Add geom_shape for drawing polygons with rounded corners and expanded/contracted sides. geom_shape replaces all geom_polygon internally.
• Added geom_bspline_closed to draw polygons defined as b-splines
• Add geom_mark_[rect|circle|ellipse|hull] to encircle a group of points and optionally add textual annotation to it
• Add position_jitternormal to jitter points based on a normal distribution (@andrewheiss)

Improvements

• facet_[wrap|grid]_paginate will now try to make panels on the last page the same size as on full pages (#7)
• facet_zoom now gains xlim and ylim arguments to control zoom range directly
• facet_zoom now gains zoom.data to control which data gets plotted in which panel
• Slimmed down the dependencies for the package. plyr, lazyeval and dplyr has all been removed
• Rewrite geom_sina to match geom_violin and allow for dodging
• Add open/clamped option to `geom_bspline

Bug fixes

• Fix interpolation of x and y values in geom_link2 (@thomasp85 and @lepennec)
• stat_link no longer replicates the group column
• arcs and links no longer rename aesthetics when only one aesthetic is present (drop = FALSE)
• stat_bezier0 and stat_bezier2 now return data in the expected format
• Fix bug with n_pages due to internal changes in ggplot2
• Fix bug in facet_zoom in combination with secondary y-axis where the space for the y-axis would become huge
• Correctly detect and error out when scales and coords does not work with facet_zoom
• The *2 versions of line geoms no longer adds an NA to guides.

ggforce 0.1.1

New features

• Zoom indicator styling can now be specified separetely for x and y zoom using zoom.x and zoom.y in theme (inherits from zoom that inherits from strip.background)

Bug fixes

• Fix bug in facet_wrap_paginate that threw errors when using it with free scales (#19)
• Fixes bug in facet_zoom where y-axis would be incorrectly displayed when zooming on both axes without splitting the view (#23)
• Fixes bug in facet_zoom where scale expansion where not taken into account when drawing the indicator area (#22)
• Fixes a bug in facet_zoom that would throw errors with layers not containing the column that is zoomed by (#21)

ggforce 0.1.0

Major changes

• geom_edge_bundle has been renamed geom_bspline and lost the tension argument. True edge bundle functionality has been moved to ggraph

New features

• geom_bezier for drawing quadratic and cubic beziers
• geom_link for augmented segment/path drawing
• geom_sina as an alternative to geom_violin and geom_beeswarm
• scale_[x|y]_unit for using units vectors
• facet_[wrap|grid]_paginate to split facetting into multiple pages
• facet_zoom for contextual zooming

ggforce 0.0.1

Major changes

• First commit

New features

• geom_arc / stat_arc for drawing circle segments
• geom_edge_bundle / stat_edge_bundle for drawing edge bundles based on control points
• geom_arc_bar /stat_arc_bar / stat_pie for drawing arcs and wedges with fill
• geom_circle / stat_circle for drawing circles with radius based on coordinate system scale
• power_trans for creating power transformations
• radial_trans for creating transformation between radial and cartesian coordinates
• trans_reverser for reversing a trans object
