**riskyr 0.3.0** is published on CRAN on March 23, 2021.

Log of changes since last release:

- Added
`plot_fnet()`

for plotting*frequency nets*(Binder et al., 2020) [2020-12].

Changed default setting of

`mar_notes`

in all plotting functions [2021-01]: Using`mar_notes = FALSE`

as those details are not needed and can be distracting in visualizations.Change default arguments for

`plot_area()`

and`plot_tab()`

[2019-01]:

Change default settings from`f_lbl_hd = "abb"`

to`f_lbl_hd = "nam"`

(as this makes more sense for riskyrApp).New options for

`plot_curve()`

[2019-01]:

Plotting probability curves as a function of prevalence does not require any specific prevalence value. Thus, setting the`prev`

argument to either`NA`

or to a vector of several probabilities is now supported. Setting the new`prev_range`

argument to a range within`c(0, 1)`

allows zooming into more specific ranges of`prev`

values (on x-axis).New options for

`plot_plane()`

[2019-01]:

Plotting a probability plane as a function of sensitivity and specificity does not require specifying all values. Thus, setting the`sens`

and`spec`

arguments to either`NA`

or to a vector of several probabilities is now supported. Setting the new`sens_range`

and`spec_range`

arguments to ranges within`c(0, 1)`

allows zooming into more specific ranges of`sens`

values (on x-axis) and`spec`

values (on y-axis).New options for

`plot_prism()`

[2019-01]:

Using the new`p_lwd`

and`p_scale`

arguments allows scaling the widths of probability links by current probability values.

`data`

[2019-07]:

Removed data files`df_scenarios.RData`

and`df_scenarios.csv`

, as they were redundant to`df_scenarios.rda`

(loaded from`\data`

).`make_cond_lbl()`

[2019-01]:

The condition label now allows for`NA`

or vectors of several values (for`prev`

,`sens`

, and`spec`

).`is_prob_range()`

[2019-01]:

Add utility function to verify a range of two probability values (to check new arguments of`plot_curve()`

and`plot_plane()`

).

Using colors of

`pal`

for fill colors of symbols in`plot_icon()`

[2021-02].Add color palettes [2019-01]:

Add

`pal_bwp`

(a strict b+w color palette suited for printing purposes) and corresponding special cases to major plotting functions.Add

`pal_unikn`

(based on color definitions of the**unikn**package).

Changes to color palettes [2019-01]:

Add a background color`pal[["bg"]]`

to all palettes and plots (to preempt different system defaults).

Adopt`pal_mod`

– rather than`pal_mbw`

– as default color scheme`pal`

(to highlight`cond_true`

and`dec_pos`

cases in default plots).

Added reference to article on theoretical background (Neth et al., 2021).

Bug fix in

`plot_prism()`

: Allow plotting simple trees for`nchar(by) == 2`

.Bug fix in

`plot_icons()`

[2019-01]: Enforce 2 different symbol types for icon arrays with a binary perspective (`by = cd`

or`dc`

or`ac`

).

**riskyr 0.2.0** was released on CRAN on January 03, 2019.

Log of changes since last release:

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.

`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).

`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`

).

More consistent argument and variable names (using snake_case).

Many additions and corrections in documentation, examples, and vignettes.

`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.
