CONS an R based graphical interface to perform Consonance Analysis

With the advent of widespread computing and availability of open source programs to perform many different programming tasks, nowadays there is a trend in Statistics to program tailor made applications for non statistical customers in various areas. This is an alternative to having a large statistical package with many functions many of which never are used. In this article, we present CONS an R package dedicated to Consonance Analysis. Consonance Analysis is a useful numerical and graphical exploratory approach for evaluating the consistency of the measurements and the panel of people involved in sensory evaluation. It makes use of several uni and multivariate techniques either graphical or analytical, particularly Principal Components Analysis. The package is implemented in a graphical user interface in order to get a user friendly package.
