Extend Rasch and Item Response Theory (IRT) analyses by providing  
 tools for post-processing the output from five major IRT packages  
 (i.e., 'eRm', 'psychotools', 'ltm', 'mirt', and 'TAM').            
 The current version provides the plotPIccc() function, which       
 extracts from the return object of the originating package all     
 information required to draw an extended Person-Item-Map (PIccc),  
 showing any combination of                                         
 * category characteristic curves (CCCs),                           
 * threshold characteristic curves (TCCs),                          
 * item characteristic curves (ICCs),                               
 * category information functions (CIFs),                           
 * item information functions (IIFs),                               
 * test information function (TIF), and the                         
 * standard error curve (S.E.).                                     
 for uni- and multidimensional models (as far as supported by each  
 package). It allows for selecting dimensions, items, and categories
 to plot and offers numerous options to adapt the output. The return
 object contains all calculated values for further processing.

Legacy 'DBI' interface to 'MySQL' / 'MariaDB' based on old code
    ported from S-PLUS. A modern 'MySQL' client written in 'C++' is available
    from the 'RMariaDB' package.
