Provides a system for reporting messages, which provides certain useful features over the standard R system, such as the incorporation of output consolidation, message filtering, assertions, expression substitution, automatic generation of stack traces for debugging, and conditional reporting based on the current "output level".

Provides an easy way to report the results of regression analysis, including:
    1. Proportional hazards regression from function 'coxph' of package 'survival';
    2. Conditional logistic regression from function 'clogit' of package 'survival';
    3. Ordered logistic regression from function 'polr' of package 'MASS';
    4. Binary logistic regression from function 'glm' of package 'stats';
    5. Linear regression from function 'lm' of package 'stats';
    6. Risk regression model for survival analysis with competing risks from function 'FGR' of package 'riskRegression';
    7. Multilevel model from function 'lme' of package 'nlme'.

Streamlined statistical reporting in 'Rmarkdown' environments. 
    Facilitates the automated reporting of descriptive statistics, multiple 
    univariate models, multivariable models and tables combining these outputs. 
    Plotting functions include customisable survival curves, forest plots from 
    logistic and ordinal regression and bivariate comparison plots.

Provides an easy way to report the results of ROC analysis, including:
    1. an ROC curve. 
    2. the value of Cutoff, AUC (Area Under Curve), ACC (accuracy),
    SEN (sensitivity), SPE (specificity),
    PLR (positive likelihood ratio), NLR (negative likelihood ratio),
    PPV (positive predictive value), NPV (negative predictive value),
    PPA (percentage of positive accordance), NPA (percentage of negative accordance), TPA (percentage of total accordance),
    KAPPA (kappa value).

These functions are especially helpful when writing reports of data analysis using "Sweave".

An R Interface to 'EPP-lab' v1.0. 'EPP-lab' is a Java program for
    projection pursuit using genetic algorithms written by Alain Berro and S. Larabi
    Marie-Sainte and is included in the package.
