Improves the user experience of Shiny apps by helping to
    provide feedback when required inputs are missing, or input values
    are not valid.

Collection of custom input controls and user interface components for 'Shiny' applications. 
  Give your applications a unique and colorful style !

Provides an XY pad input for the 'Shiny' framework. An XY pad is like a bivariate slider. It allows to pick up a pair of numbers.

 Most useful functions:
 Bclust(), Jclust() and BootA() which bootstrap hierarchical clustering;
 Recode() which does multiple recoding in a fast, simple and flexible way;
 Misclass() which outputs confusion matrix even if classes are not concerted;
 Overlap() which measures group separation on any projection;
 Biarrows() which converts any scatterplot into biplot;
 and Pleiad() which is fast and flexible correlogram.

Block-diagonal covariance selection for high dimensional Gaussian
    graphical models. The selection procedure is based on the slope heuristics.

Provides tools for shoreline dating coastal Stone Age sites. The 
  implemented method was developed in Roalkvam (2023) 
  <doi:10.1016/j.quascirev.2022.107880> for the Norwegian Skagerrak coast. 
  Although it can be extended to other areas, this also forms the core area for 
  application of the package. Shoreline dating is based on the present-day 
  elevation of a site, a reconstruction of past relative sea-level change, and
  empirically derived estimates of the likely elevation of the sites above the 
  contemporaneous sea-level when they were in use. The geographical and temporal 
  coverage of the method thus follows from the availability of local geological 
  reconstructions of shoreline displacement and the degree to which the 
  settlements to be dated have been located on or close to the shoreline when 
  they were in use. Methods for numerical treatment and visualisation of the 
  dates are provided, along with basic tools for visualising and evaluating the 
  location of sites.
