ggformula

ggformaul 0.12.1

• Bug fix in gf_dist()

ggformula 0.12.0

• Removed dependency on ggstance so that ggformula can work with WebR
• Deprecated horizontal versions of many plotting functions to remove dependence on ggstance and because ggplot2 now supports horizontal versions of most geoms.
• Examples have been updated to use |> rather than %>%
• Updates to documentation (formatting mostly)
• Bug fix: found one remaining use of stat() and changed to after_stat()

ggformula 0.10.4

• Updated the re-export of a few functions from labelled. (#160)
• Migrated from stat() to after_stat() to avoid deprecation notices from ggplot2. (#156)
• Migrated from size to linewidth for line-like geoms to avoid deprecation notices from ggplot2. (#155)

ggformula 0.10.2

• Added improvements to gf_hline(), etc. responding to changes in {ggplot2}. See #128.
• Added support for nonsyntactic names in formulas. Among other things, this allows for using backticks around such names. See #152 and #153
• Added examples of gf_lm() with non-default models.

ggformula 0.10.0

• Added gf_ridgeline(), gf_ridgeline_gradient(), gf_density_ridges(), gf_density_ridges_gradient().
• gf_dens() now uses geom = "geom_density_line". This allows setting fill.
• Plots now label variables with labels created in data using labelled, expss or Hmisc labeling functions
• To reduce the size of the package, the main vignette has been shortened. The full version is available at https://www.mosaic-web.org/ggformula/.
• Two other vignettes have been moved to online only for the same reason.

ggformula 0.9.4

• internal updates precipated by changes to ggplot2.

ggformula 0.9.3

• add gf_sina(). (#134)
• update exampels involving sf::st_as_sf() to reflect updated names of in the resulting data frame. This is required to get CRAN builds to work without an error. (#137)
• Add helpful error message if dist is not a string in gf_dist(). (#133)

ggformula 0.9.2

• Some internals in layer_factory() have been reimplemented to avoid making copies of ggplot2 functions at compile time. This should make things more stable when updating ggplot2 but not updating ggformula.
• Two new graphing functions were added: gf_ellipse() and gf_ecdf()
• gf_rugx() and gf_label() have been modified a bit to make them easier to use.
• Evaluation environments are now handled more stably. Instead of using the environment of the formula, the environment argument is used. After some delay, this completes the migration to ggplot2 version 2.2 (#96, #125)
• Bug fix in gf_dist() to avoid an error when using params. (#119)
• Default in gf_errorbar() is now inherit = TRUE. The old default was required due to inconvenient naming of aesthetics in geom_errorbar(), but those names have been changed now. (#120)
• New function: discrete_breaks().

ggformula 0.9.1

This release includes a few minor improvements, including

• Updated examples so they work better with pkgdown
• Other document improvements

ggformula 0.9.0

• ggformula now requires ggplot2 (>= 3.0.0). This should take care of issues in 0.8.0 when ggplot2 was upgraded after upgrading ggformula.
• pkgdown website created at https://www.mosaic-web.org/ggformula/
• Several horizontal versions of geom and stats are implemented using ggstance.
• vdiffr is used for testing plot output

ggformula 0.8.0

• The internals of all of the gf_ functions have been modified to make them work with ggplot2 version 2.3. In future releases, a version ggplot2 at least this new will be required.

• The default value for se in gf_smooth() has been changed from TRUE to FALSE.

• gf_sf() added to support simple features data for maps.

• improved documentation and examples

ggformula 0.7.0

• Formulas of the shape y ~ . can be used for plots that require a y aesthetic but no x aesthetic.
• Added gf_rugx() and gf_rugy(). Also additional examples using rugs are given in the documentation.
• Added gf_polygon() for simple maps. (Improved mapping capabilities should be coming when ggplot2 hits version 2.3.)
• Some internals have been reworked to improve the processing of arguments and deciding when to display the quick help for plotting functions.
• Modifications to the environments in which some functions are evaluated.

ggformula 0.6.2

• Improved scoping of gf_ functions makes it easier to work with data in the global environment.
• New functions gf_props() and gf_percents() added to simplify creating bar graphs on a proportion or percent scale.
• New arguments xlab, ylab, title, subtitle, and caption added to gf_ functions. In the case of gf_props() and gf_percents() these are prepopulated with defaults of "proportion" and "percent" to give nicer labeling of the plot.
• The use of weatherData has been removed since that package is no longer on CRAN
• Improvements to gf_abline(), gf_hline(), and gf_vline() expand the usable portion of the API.
• Additional examples for some functions.

ggformula 0.6.1

Minor update primarily to support vignette data sets moving from StatisticalModeling to mosaicModel.

• Also added gf_fitdistr().

ggformula 0.6.0

Mostly minor changes:

• Improved documentation of gf_ functions.
• na.warn() is now re-exported.
• Bug fix in gf_violin().
• Reformatted quick help messages.

ggformula 0.5.0

For version 0.5, the internals of ggformula have been largely redesigned to allow implementation of some new features. The new version relies much less on string parsing.

• Some important changes to formula parsing include

  • attribute:value and attribute::expression are no longer supported within the main formula.
  • In exchange, things like gf_point(1:10 ~ 1:10) work, making it simpler to create on the fly plots without having to build a data frame first.
  • y ~ 1 is equivalent to ~ y in functions that allow the ~ y formula shape. Example: gf_histogram(age ~ 1) and gf_histogram( ~ age) are equivalent

• Some new functions have been added

  • gf_dist() can plot distributions
  • gf_dhistogram() plots density histograms by default
  • gf_ash() creates ASH plots

• df_stats() has been improved to handle one-sided formulas better.

• Secondary layers are now able to inherit both data and formula-defined attributes from the primary layer. Use inherit = FALSE if you don't want inheritance. (A few functions have inherit = FALSE as their default because it seems unlikely that inheriting will be desireable.)

ggformula 0.4.0

Version 0.4.0 constitutes a stable beta release. Changes to the API are still possible, but more likely future changes will focus on expansion of the suite of functions supplied, changes to the internal implementation, and improved documentation.

• Separated ggformula from statisticalModeling.
• Added support for many more geoms.
• Improved parsing of formulas. This is still a bit clunky since the order of operations in R formulas does not match what we would prefer in this package.
• data may now be an expression (like data = KidsFeet %>% filter(sex == "G"))
• Added support for geoms that have different required aesthetics.
• Added support for functions that allow more than one formula shape. Example: gf_histogram() accepts formulas with shape ~ x or y ~ x. This makes it possible to create density histograms with gf_histogram().
• Parentheses now halt parsing of formulas. This allows for on-the-fly computations in formulas. Typically these computed expressions must be within parentheses to avoid formula expansion.
• Use :: to indicate mapping aesthetics. (: will autodetect, but only if the value is the name of a variable in the data set.) This should be considered experimental.
• Added wrappers gf_lims(), gf_labs(), gf_theme(), gf_facet_grid(), gf_facet_wrap()
• Added gf_refine() which can be used to pass by chaining anything that would have been "added" in ``ggplot2`
• Expanded and improved vignette describing use of the package.
• Added two tutorials.
• Added "quick help" for plotting functions.
• Added gf_lm(), which is gf_smooth() with method = "lm"
• Added gf_dens() which is gf_line() with stat = "density".
