`pal`

is initialized to a vector of named elements (colors)
to define the scenario color scheme that is
used throughout the `riskyr`

package.

`pal`

An object of class `character`

of length 16.

All color information corresponding to the current scenario
is stored as named colors in a vector `pal`

.
To change a color, assign a new color to an existing element name.

`pal`

currently contains colors with the following names:

`N`

Color representing the*population*of`N`

cases or individuals.`cond_true`

Color representing cases of`cond_true`

, for which the current condition is`TRUE`

.`cond_false`

Color representing cases of in`cond_false`

, for which the current condition is`FALSE`

.`dec_pos`

Color representing cases of`dec_pos`

, for which the current decision is`positive`

.`dec_neg`

Color representing cases in`dec_neg`

, for which the current decision is`negative`

.`dec_cor`

Color representing cases of correct decisions`dec_cor`

, for which the current decision is`accurate`

.`dec_err`

Color representing cases of erroneous decisions`dec_err`

, for which the current decision is`inaccurate`

.`hi`

Color representing*hits*or true positives in`hi`

(i.e., correct cases for which the current condition is TRUE and the decision is positive).`mi`

Color representing*misses*or false negatives in`mi`

(i.e., incorrect cases for which the current condition is TRUE but the decision is negative).`fa`

Color representing*false alarms*or false positives in`fa`

(i.e., incorrect cases for which the current condition is FALSE but the decision is positive).`cr`

Color representing*correct rejections*or true negatives in`cr`

(i.e., correct cases for which the current condition is FALSE and the decision is negative).`ppv`

Color representing*positive predictive values*`PPV`

(i.e., the conditional probability that the condition is TRUE, provided that the decision is positive).`npv`

Color representing*negative predictive values*`NPV`

(i.e., the conditional probability that the condition is FALSE, provided that the decision is negative).`txt`

Color used for text labels.`brd`

Color used for borders.`bg`

Color used for plot background (used to set`par(bg = bg_col)`

).

Note that color names for frequencies correspond to frequency names,
but are different for probabilities (which are written in lowercase
and only `PPV`

and `NPV`

have assigned colors).

`init_pal`

initializes color information;
`num`

contains basic numeric parameters;
`init_num`

initializes basic numeric parameters;
`txt`

contains current text information;
`init_txt`

initializes text information;
`freq`

contains current frequency information;
`comp_freq`

computes current frequency information;
`prob`

contains current probability information;
`comp_prob`

computes current probability information.
