In plot3logit: Ternary Plots for Trinomial Regression Models

plot3logit 3.1.3

Minor changes

• Added references and citations to the JSS article about the package.

plot3logit 3.1.2

Typos and other marginal changes

• Revision of help and references.

plot3logit 3.1.1

Major changes

• Solved a bug on add_confregions() (class of returned objects).

plot3logit 3.1.0

Major changes

• Implemented the syntax based on named numeric for argument delta of field3logit().
• Solved a bug on method dispatch of generic autoplot for class multifield3logit.

Minor changes

• Revised and extended the vignette plot3logit-overview.
• Corrected a bug on argument label of field3logit() and added tests.
• Corrected a bug on method label<- and added tests.
• Provided statistical details on the computation of confidence regions in the help of add_confregions().

Typos and other marginal changes

• Corrected file CITATION and list of authors of the vignette plot3logit-overview.
• Syntactical revision of tests.

plot3logit 3.0.0

Major changes

• Changed dependencies of the package both in section "Imports" (added stringr) and "Suggests" (added ordinal and testthat).
• Implemented syntax for factor covariates based on delimiters <<...>>.
• Implemented the generic export3logit() and several S3 methods for reading output from fitted models.
• Revised the arguments of field3logit(): arguments alpha and vcov are now deprecated and does not work any more.
• Argument model of field3logit() cannot accept matrices any more. Direct model estimates can be passed to field3logit() by means of a list.
• Now field3logit() can read also trinomial models fitted through function vglm of package VGAM, and functions clm and clm2 of package ordinal (included amongst suggested packages).

Minor changes

• Introduced class model3logit as output of export3logit().
• Renamed component lab of field3logit and multifield3logit objects to levels.
• Redefined classes and inheritance of field3logit and multifield3logit. objects.
• Revised coef method for field3logit objects of ordinal models.
• Redefined the output of plot.multifield3logit and remove the legend.

Typos and other marginal changes

• Revised the help and the examples.

plot3logit 2.2.0

Major changes

• Now plot3logit depends on R v. 3.5 or later.
• Now field3logit can read categorical trinomial models fitted through function vgam of package VGAM (included amongst suggested packages).
• list objects can be passed to argument delta of field3logit for computing multiple fields (a multifield3logit object is returned).
• Argument ncurves of function field3logit has been renamed to nstreams. No backward compatibility has been implemented.
• Point estimates are passed to argument model of field3logit, matrix should have an attribute with the values the dependent variable may take. The attribute has been renamed from labs to levels. No backward compatibility has been implemented.
• Added package generics amongst dependencies in section Imports.

Minor changes

• Added dataset USvote2016.
• Corrected bug on reading ordinal models from matrix.
• Added S3 methods of generics tidy for class field3logit.
• Added S3 methods of generics as.data.frame, as_tibble and tidy for class multifield3logit.
• Made autoplot the S3 method of generic autoplot for field3logit objects
• Added S3 method of generic label for class field3logit.
• Added S3 method of generic label for class multifield3logit.
• Added S3 method of generics [ and [<- for multifield3logit class.
• Added the generic labels<- and the S3 methods for field3logit and multifield3logit class.

Typos and other marginal changes

• Removed names from components of multifield3logit objects.

plot3logit 2.1.0

Major changes

• Major bug corrected from version 2.0.0.

plot3logit 2.0.0

Major changes

• Added functions for computing the confidence regions of the covariate effects of categorical trilogit models and function for representing confidence regions both in standard an gg graphics.
• Changed dependencies of the package both in section "Depends" (updated the version of ggtern) and in section "Imports" (added dplyr, forcats, grDevices, lifecycle, purrr, Rdpack, tibble, tidyr, tidyselect and removed reshape2).
• Added the plot function for multifield3logit in standard graphics.
• Updated the functions for reading the output of mlogit according to the upcoming new version of the package. The package plot3logit handles the output of both the current and the upcoming version of mlogit.
• Completely redefined the output of methods as.data.frame and fortify for objects of class field3logit and multifield3logit.
• Function plot3logit is now deprecated and not updated.
• Partially redefined function stat_3logit and added function stat_field3logit which works like the previous version of stat_3logit.

Minor changes

• Added methods coef and vcov for objects of class field3logit and multifield3logit.

Typos and other marginal changes

• Added zero element (NULL) in the sum of field3logit and multifield3logit.
• Added attribute ordinal to S3 class field3logit and updated the S3 method print.

plot3logit 1.0.2

Major changes

• Vignette plot3logit-overview has been added to the package.
• Updated dependencies by including package "ellipse" amongst imported packages.

Minor changes

• The level Long of variable irregulariry of dataset cross_1year has been changed to High.

Typos and other marginal changes

• Updated references to Santi, Dickson and Espa (2019).

plot3logit 1.0.1

Major changes

• Bug solved for as.data.frame.field3logit when a zero-coefficient model is passed to field3logit. The previous version was not able to return a data.frame correctly built. Functions stat_3logit, and TernaryField have been adapted so as to draw points instead of arrows.

Minor changes

• Interface of fortify methods has been redefined by including argument data, so that now all fortify methods of the package are compliant with the interface of the generic.

• field3logit now can read categories labels of the dependent variable from attribute labs when argument model is a matrix. Example in the help of package presentation has been updated.

Typos and other marginal changes

• CITATION file has been amended: the title of the package and other typos have been corrected.

• Revision of the file README.md.

plot3logit 1.0.0

First release of the package plot3logit on CRAN!
