Log of changes since last release:

Major changes

New riskyrApp version [2018-12]:
To use selected riskyr functions without the need for coding
an updated version of riskyrApp is available
at https://github.com/hneth/riskyrApp (R Shiny code) and
at http://riskyr.org (interactive online version).
Using pkgdown [2018-12]:
Provide package documentation online at https://hneth.github.io/riskyr (latest release version) and https://hneth.github.io/riskyr/dev/ (current development version).

Retiring obsolete functions [2018-12]:
The functions plot_fnet and plot_tree are replaced by plot_prism, and plot_mosaic is replaced by plot_area. This improves functionality (e.g., by providing more consistent options across different plotting functions) and removes dependencies on external packages.
New plot_prism function [2018-11]:
Show a scenario as double frequency tree (by 3 x 2 perspectives) or a frequency tree (in 3 perspectives) with many additional options; replaces the older plot_fnet and plot_tree functions (and removes dependency on the diagram package).
New plot_area function [2018-10]:
Show a scenario as a mosaic plot of relative proportions (in 3 x 2 x 2 possible versions, with many additional options); replaces the older plot_mosaic function (and removes dependencies on the grid and vcd packages).
New plot_tab function [2018-10]:
Show a scenario as contingency table of frequencies (with row and column sums, and options for showing probabilities);
a variant of plot_area that does not scale area sizes.
New plot_bar function [2018-08]:
Show scenario frequencies as vertical bars (in various configurations).

Create plot_util.R collection of graphical utility functions [2018-08]:
Define a new box object type and various functions for plotting, labeling, and linking them in graphs
(to remove dependencies on and limitations imposed by other packages).
Updated riskyr function [2018-03]:
As an alternative to providing 3 essential frequencies, it is now possible to define a scenario from 4 essential frequencies (and check for consistency with given probabilities).

Improved plot_icons function [2018-12]:
Show icons separated into 2 subsets by 3 perspectives (condition, decision, accuracy), using the same by argument as the other plotting functions.
plot_curve and plot_plane functions [2018-11]:
Update variable names (to snake_case) and add arguments (e.g., col_pal, lbl_txt mar_notes, etc.) for consistency with newer plotting functions.
scale argument [2018-10]:
The new plotting functions feature a scale argument that allows scaling the size or areas of boxes either by (exact) probability or by (possibly rounded) frequency. When using scale = "f", the probabilities shown are also re-computed from (possibly rounded) frequencies.
plot_fnet [2018-02]:
Change argument box.cex to cex.lbl to ensure consistency with plot_curves and plot_plane (and use it to scale arrow labels accordingly). Added warning when using deprecated argument.
plot_mosaic [2018-02]:
Change Boolean vsplit argument to by = "cd" vs. by = "dc" to ensure consistency with plot_fnet and plot_tree. Added warning when using deprecated argument.
mar_notes and plot_mar [2018-09]:
Use consistent plot margins and options for showing margin notes for all plots.

read_popu [2018-11]:
Read a data frame popu and interpret is as a riskyr scenario, allows creating scenarios from raw data.
comp_accu.R [2018-08]:
Compute exact accuracy values (not approximations, when using comp_accu_freq on rounded freq values) by using the new function comp_accu_prob to compute the list accu from probabilities. Signal rounding when showing accuracy based on rounded frequencies in plots (when show.accu == TRUE and round == TRUE).

pal and freq [2018-12]:
Use more consistent color and frequency names (e.g., cond_true, dec_pos, and dec_cor are now names of frequencies and the colors corresponding to these frequencies).
freq [2018-07]:
Add a 3rd perspective (by accuracy or by correspondence of decision to condition) and corresponding frequency pair of dec.cor and dec.err (i.e., hi + cr vs. mi + fa as the diagonal of 4 SDT cases). This increases the number of frequencies in freq from 9 to 11. Also added corresponding labels in init_txt.R and colors in init_pal.R.
prob [2018-09]:
Include accuracy metrics in probabilities (in prob and summary functions).
pal and txt [2018-10]:
Add multiple color palettes and text labeling schemes (see ?pal and ?txt for details).

plot_icons [2018-03]:
Bug fix to also swap symbols in legend when the symbol order is changed manually.
txt_def [2018-02]:
Simplify some default text labels (e.g., for current population, condition, and decision).
.onAttach [2018-02]:
Cast dice to display probabilistic (i.e., risk-related) start-up messages.
